Question
The difference between the length and breadth of a
rectangle is 27 m. If its perimeter is 194 m, then its area isSolution
Using formula, Perimeter = 2(l + b) Ā Let the breadth be āxā metre Length = (27 + x) metre ā 2(x + 27 + x) = 194 ā 4x = 194 ā 54 ā x = 140/4 = 35 metre Therefore, length = 35 + 27 = 62 metre Therefore, required area = 62 x 35 = 2170 mĀ²
