Question

a rod 86 cm long is bend in the form of rectangle such that its length is 7 cm greater its breadth. find length and breadth

Answer 1

Total length = perimeter
________________

Let the breadth be x cm
Length be (x+7) cm
____________

86=2(length + breadth)

86=2(x+x+7)

86/2 = 2x+7

43=2x+7

43-7=2x

36=2x

36/2=x

18 = x

Now,

Breadth = x = 18cm
Length = (x+7) cm = 18+7=25 cm
