Question
The difference between the length and breadth of a
rectangle is 25 m. If its perimeter is 206 m, then its area isSolution
Using formula, Perimeter = 2(l + b) Let the breadth be ‘x’ metre Length = (25 + x) metre ⇒ 2(x + 25 + x) = 206 ⇒ 4x = 206 – 50 ⇒ x = 156/4 = 39 metre Therefore, length = 39 + 25 = 64 metre Therefore, required area = 64 x 39 = 2496 m²
