55 = l + 23

l = 32m

Answer 2

Given :

The cost of fencing a rectangular field at Rs. 18 per metre is Rs. 1980 if the width of the field is 23 cm

To Find :

Find its length.

Solution :

The perimeter of the rectangular field

➵ 1980/18

➵ 110 cm

Breadth of the field = 23 m.

Perimeter = 2( L + B )

➵ 110 cm = 2 ( L + 23 )

➵ L + 23 = 55

L = 32m

Therefore ,

The length of the field is 32m.
