Question

A write of length 86cm is bent in the from of a rectangle such that it's length is 7cm more than its breadth find the length and breadth of the rectangle so formed

Answer 1

Answer:

86 cm is the perimeter of the rectangle

2(l+b)=86

breadth = x

length =x+7

2(x+x+7)=86

2(2x+7)=86

2x+7=43

2x=43-7=36

x=36/2=18cm

breadth = 18cm

length = 18+7=25 cm

(checking 2(18+25)=2(43)=86)
