Step 1: Given the length of the rectangle 20 units, breadth of the rectangle 5 units Step 2: Area of rectangle formula length x breadth Step 3: 20 x 5 100 Step 4: The area of the rectangle is 100 square units. If 25 cm is the length of the sheet, find its width. We’ll calculate the area of a rectangle with a length of 20 units and a width of 5 units. Q: The area of a rectangular sheet is 500 cm². Solution: Length of the blackboard 120 cm 1. So, cost of painting the total area of the rectangular land = 0.50 x 150000 = Rs 75000. Area of a rectangle Length × Width 15 × 4 60 So the area of rectangle 60 cm 2 Example 2: Find the area of a rectangular blackboard whose length and breadth are 120 cm and 100 cm, respectively. 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. Since all 4 sides of a square are equal, the base and height. Here, in the case of a rectangle, its length and breadth are not equal. Look at the above square and recall the formula for the area of a rectangle: Area base × height. 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. 2 Solved Examples Area of Rectangle Formula
