Answer 2

Answer:

Let L and B be length and breadth of the rectangle.

L=2B (given)

perimeter = 2x(l + b)

Jamal jogged around four times and covered the distance of 6 km .

4 x [2 x ( L + B)] = 6

4 x 2(L+B) = 6

8 x (L + B) = 6

8 x (2B + B) = 6 ( as L = 2B)

8 x 3B = 6

24B = 6 x 1000 = 6000

B = 6000/24

= 250m

The length of the field = 2 x 250 = 500m
