Question

Shilpa runs along a rectangular field twice and covers a distance of 540 metre if the length of the field is 75m
find its breadth and area​

Answer 1

Total distance covered = Distance covered in 2 rounds

Distance covered in 2 rounds = 540 m

Distance covered in 1 round = 540/2

= 270 m

So, Perimeter of the field = 270 m

2(l+b) = 270

l+b = 270/2

l+b = 135 m

Length (l) = 75 m

Breadth = b

75+b = 135 m

b = 135-75

b = 60 m

Breadth = 60 m

Area of that field = Length×Breadth

= 75×60

Area of that field = 4500 m²
