Question

A rectangular plot is 180 sq. metres in area . If its length is 18 m , find its perimeter

Answer 1

Given,
area of a rectangular plot is = 180 m^2
length of the rectangular plot is = 18 m
breadth of the rectangular plot is = x
18× x= 180
x=180/18
x=10
therefore perimeter of the rectangular plot is = 2(l+b)
= 2(18+10)
= 2(28)
=56
therefore perimeter of the rectangular plot is 56m

Answer 2

Area of rectangualr plot=180cm²

lb=180

18(b)=180

b=180/18

b=10

Breadth=10m

Perimeter of rectangular plot=2(l+b)

=2(18+10)

=2(28)

=56m
