Question

9. The length of a football ground is 100 m and its width is 40 m. Find the perimeter of the
ground. Also, find the cost of fencing it with wire at the rate of 2.50 per metre.
​

Answer 1

Length = 100m

Width = 40m

Perimeter = 2(l+b)

2(100+40)

2(140)

Perimeter = 280m

Cost of fencing per metre = 2.50rs

Cost of fencing whole ground = 280/2.5

2800/25

112 rs

So, 112 rs is the total cost

Hope it helps :)

Answer 2

Answer:

length of ground is 100m

width of ground is 40m

perimeter of ground=2(l+b)

=2(100m+40m)

=2x 140m

=280m
