Question

the length of a rectangle is 8 cm more than its breadth. if its perimeter is 112 cm, then its length and breadth are respectively.

Answer 1

Answer:

Breath = 24 cm and Length = 32 cm

Step-by-step explanation:

Let the breath be α cm then the length is α + 8 cm.

Perimeter  = 112 cm

2( l + b)      = 112                         [ perimeter of rectangle = 2(l+ b)]

2( α + α + 8)  = 112

2α + 8 = 112/2

2α = 56 - 8

2α = 48

α = 24 = breath

α + 8 = 32 = length
