Question

The perimeter of a rectangle is 72 cm.Its length is 25 cm. Find its breadth

Answer 1

Perimeter of rectangle = 2 ( l + b )

72 = 2 ( 25 + x )

72 = 50 + 2x

2x = 72 - 50

x = 22/2

x = 11

So , the breadth of rectangle is 11 cm .

Answer 2

Answer:

perimeter=2*(l+b)

72=2*25+x

72=50+2x

72-50=2x

22=2x

x=22/2

breath is 11cm
