Question

It cost ₹ 5400 to fence a square field at ₹13.50 per meter. find (i) the length of the side of the field (ii) the area of the field.

Answer 1

perimeter of field=5400/13.5
4a=400
a=400/4=100m
side=100m
area of field=side
=100²=10000m²
thus area of field is 10000m²

Answer 2

Dear Student,

● Answer -

Length of square field = 20 m

Area of square field = 400 sq.m

◆ Explaination -

Area of the field is calculated as -

Area of field = 5400 / 13.5

Area of field = 400 sq.m

Length of square field is -

Length = √400

Length = 20 m

Hence, length of side of square field is 20 m and area is 400 sq.m.

Thanks dear. Hope this helps you...
