The perimeter of a rectangle is 130 cm. If the breadth of the rectangle is 30 cm, find its length. Also, find the area of the rectangle. |

Answer» Perimeter of rectangle = 130 cm ⇒ 2 (length + breadth) = 130 cm ⇒ 2 (length + 30) = 130 ⇒length + 30 = 130/2 ⇒length + 30 = 65 ⇒length = 65 – 30 = 35 cm Now area of rectangle = length x breadth = 35 x 30 = 1050 cm2 Thus, the area of rectangle is 1050 cm2. |
