Question

The perimeter of a rectangular sheet is 160cm. If its length is 54cm, find its breadth

Answer 1

Perimeter of rectangle=160cm^
Length of sheet=54cm
Perimeter=2(l+b)
160=2(54+b)
160/2=54+b
80-54=b
=26
So breadth of rectangular sheet is 26cm

Answer 2

2(l+b)=160
2(54+b)=160
54+b=160/2
54+b=80
b=80-54
b=26
