Question

A square of a field has a side of 12m. What is the area of the field?

(1) 144 square cm
(2) 296 square cm
(3) 444 square cm
(4) 72 square cm​

Answer 1

Answer:

Perimeter of the square field = 4 x side = 4 x 70 m = 280 m Perimeter of rectangular field = 2 (length + breadth) = 2 (50 m + 40 m) = 2 x 90 m = 180 m ∴ Square field has greater perimeter by 280 m – 180 m = 100 m
