Question

The breadth of a rectangular park is of 48 m. If 3 km 72 m long wire is required for
fencing it, find the length of the park.
​

Answer 1

Answer:

Breadth =b=48m

length =l

perimeter =3km 72m=3072m

2(l+b)=3072

l+b=3072/2

l+48=1536

l=1536 -48

l=1488m wire required to fencing the park.

Hope this is helpful for you.

Answer 2

Answer:

Length of wire in m = (3×1000)+72 = 3000+72 = 3072

Let length be 'L' and breath be 'B'

ATP :

2(L+B) = 3072

2(L+48) = 3072

L+48 = 3072/2

L+48 = 1536

L = 1536-48

L = 1488

Length of park is 1488m or 1km 488m
