Question

a wire of length 86 cm is in is bent in the form of a rectangle such that its length is 7 cm more than its breadth find the length and breadth of the rectangle so formed

Answer 1

so the perimeter of the rectangle is 86cm
consider the breadth as x
then length is 7+x
perimeter=2(l+b)=86
2(7+x+x)=86
7+2x=43
2x=36
x=18cm
breadth=18cm
length=x+7=25cm
