The length and breadth of a rectangle are in the ratio 3 : 2. If its perimeter is 730 cm, what is the area of the rectangle? |
31,974 cm2 24,452 cm2 20,567 cm2 28,976 cm2 |
31,974 cm2 |
We know that, Perimeter of rectangle = 2(L + B) , Area of rectangle = L × B We have, Perimeter of Rectangle = 730 cm Let, the length = 3a Breadth = 2a 2(3a + 2a) = 730 = a = 73 so , length = 3a = 3 × 73 = 219 cm Breadth = 2a = 2 × 73 = 146 cm Area of rectangle = 219 × 146 = 31974 cm2 |
