Question

the cost of fencing a rectangular field 35 M long and 22 M wide at rupees 24
.50 per metre is

Answer 1

Given: length=35 m
breadth=22m
perimeter of the rectangular field=2(l+b)
=2(35+22)
=2×57
=114m
cost of fencing per meter=₹24.50
cost of fencing 114m=₹24.50×114
=₹2793

Answer 2

we know that perimeter of a rectangle = 2(l+b)

l = 35m : b = 22m

perimeter = 2(l+b) = 2(35 m+22m) = 2( 57m) = 114m

cost per meter for fencing = 24.50 rs

total cost will be = 114 * 24.50 = 2793 rs
