![]() Sample Problem 2: A square piece of wood has sides that are 2 meters long. Solution: Using the formula for the perimeter of a square: P square = 4s = 4(10) = 40 cm Sample Problem 1: A square has a side that measures 10 cm. Therefore, the perimeter of a square is just four times the measurement of its side. Determine the total distance traveled by car throughout its trip, assuming that the distance from Main Park to the Heritage Museum and “All around” Supermarket to Main Park is equal. Finally, the “All around” Supermarket car drove back to Main Park. After a 3-hour visit to the museum, the car drove another 600 meters from Heritage Museum to the “All around” Supermarket. Sample Problem 3: A car drove 1200 meters from Main Park to the Heritage Museum. To find the perimeter of an equilateral triangle, you can just simply multiply the measurement of a side of a triangle by 3. Solution: Mela’s triangle is equilateral since all of its sides are equal in length. A side of Mela’s triangle is 15 cm in length. Mela wants her triangle to have sides that are all equal in length. Sample Problem 2: Mela cut a triangle from a piece of cartolina paper. Using the formula for the perimeter of a triangle: Sample Problem 1: Calculate the perimeter of a triangle whose sides have lengths of 10 cm, 12 cm, and 15 cm. Where s is a side of the equilateral triangle. Now, if the given triangle is an equilateral triangle (which means that all of its sides are congruent or equal in measurement), then its perimeter can be calculated as: ![]() What does “perimeter” mean? How about “area”? How do you compute the perimeter and area of plane figures? These are the questions we are going to answer in this reviewer. Basically, perimeter and area are the concepts we use to quantitatively describe a certain plane figure. These concepts are always involved as long as we are dealing with plane figures such as triangles, squares, rectangles, trapezoids, and so on. These are just a few examples of how significant the geometric concepts of perimeter and area are. On the other hand, if you want to determine how much is certain land property, you need to know how many square meters it is – in this case, you are actually asking for the area of that property. If 25 cm is the length of the sheet, find its width.If you want to determine how many meters of fencing materials you need to enclose your backyard, you are actually asking for the perimeter of your backyard. Q: The area of a rectangular sheet is 500 cm². So, cost of painting the total area of the rectangular land = 0.50 x 150000 = Rs 75000. Now, let us calculate the cost of painting the land.Ĭost of painting of an area of 1 square meter = Re 0.50 Thus, Area of the rectangle A = 500 m x 300 m = 1, 50,000 square meters. Also, find the cost of painting the sheet, if a painting of an area of one square meter costs 50 paise.Īns: The Area of a rectangle (A) = l x b, where l is the length and b are the breadths of the rectangle. Q: The length and the breadth of a rectangular piece of land are 500 m and 300 m respectively find its area. Now that we have some clarity about the concept and meaning of area of rectangle, let us try some examples to deepen our understanding of the subject. Let us now take a deep look into the formula. The unit of area of the rectangle is square units. ![]() The area of a rectangle is the product of its two sides, multiplying the length and its breadth. ![]() Here, in the case of a rectangle, its length and breadth are not equal. Because of this property, we say that the two diagonals of a rectangle are congruent.Īn object in two-dimensional geometry must have measured for length and breadth. Diagonal is a line that is drawn inside the rectangle connecting the opposite corners or vertices. Another property of a rectangle is that has two diagonals of equal length. It is an equiangular rectangle with four right angles which is 90 degrees. Since a rectangle has four sides, it has four angles. The opposite sides of a rectangle are parallel and of equal length. A rectangle is a quadrilateral with four sides. Let us first understand the shape and structure of a rectangle. In this article, we will mainly be focusing on the understanding of the area of rectangle formula with some practical examples, its calculation, and units. There are different geometrical closed shapes that exist namely square, rectangle, triangle, circle, etc. The measure of the surface enclosed by a closed figure is known as its area. All the objects that lie in a plane acquire some region of a flat surface. We all know that we need some measure to compare them. We compare the objects on the basis of their size and area. When we talk about some plane figures, we think of their shape, region or boundary.
