Question

length of a rectangle exceeds its breadth by 5 M if the perimeter of the rectangle is 90 find its length and breadth

Answer 1

Let, the length of rectangle be x.
Then, breadth=(x+5)m.
perimeter of rectangle=90m.
A/Q,
perimeter of rectangle=2(l+b).
90=2(x+x+5)
90=2(2x+5)
90=4x+10
90-10=4x
80=4x
x=80/4
x=20
Hence, length=20m
breadth=(20+5)=25m
