Question

The area of arectangle is 120sq.m if its breath is 12m then its perimeter

Answer 1

Area of rectangle= 120sq.m
Breadth= 12m, let l be x
As we know, l×b= area of rectange
x*12= 120
x = 120/12
x = 10
That's why the length of rectangle is 10m
That's why perimeter = 2(l+b)
= 2×(12+10)
=2×22
=44
That's why the perimeter of the rectangle is 44m
