Question

Kishore walks around a rectangular ground having length 250 m if the area of the ground is 50000 square m , find its breadth if he takes 6 rounds of it, how long does he work?

Answer 1

area of rectangle = l×b

l×b = 50000

250×b=50000

b = 50000/250

b = 200

1rounds= perimeter of rectangle

2(l+b)

2(200+250)

2(450)

900

perimeter of rectangle=900

6 rounds= 900×6

6 rounds= 5400
