Question

A square field has each side 70m whereas a rectangular field has length = 50m and

breadth = 40m. Which of the two fields has greater perimeter and by how much?

Options are :

$180$
$120$
$140$
$160$
​

Answer 1

Answer:

Perimeter of the square field = 4 x side = 4 x 70m = 280m 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

Answer 2

the perimeter of square is 280 cm

the perimeter of rectangle is 180 cm

hence, there's a difference of 100 and the perimeter of square is greater
