WebLet the breadth of park be xHere, length = 24 m and perimeter = 84 mWe know that,Perimeter of rectangle = 2 × ( l e n g t h + b r e a d t h)Therefore,Perimeter of the park = 2 × ( x + 24)⇒ 84 = 2 x + 48 ⇒ 84 - 48 = 2 x ⇒ 36 = 2 x ⇒ x = 36 2 ⇒ x = 18 mNow, Area of rectangle is given by = l e n g t h × b r e a d t hTherefore,Area of ... WebApr 11, 2024 · Here are some solved examples based on the area and perimeter formulas of different shapes. Example 1: If the radius of a circle is given as 7cm. Find its area and circumference. Solution: Given that radius = 7cm. We have, Area A = π × r2. A = 22/7 × 7 × 7. A = 154 cm2. And Circumference, C = 2πr. C = 2 x 22/7 x 7. batch plant lake mead
