Question

The length of a rectangle is 5m greater than the width. The perimeter is 150m. Find the width and the length.

Answer 1

let length be b+5 and breadth be b

given,

perimeter of rectangle=150

or, 2(l+b) =150

or, 2(b+5+b)=150

or, 2b+5=150/2

or, 2b+5=75

or, 2b=70

therefore, b=35m

l=b+5

=35+5

=40m
