Question

a wire of length 36 cm is bent in the form of rectangle such that its length is 7 cm more than its breadth. find the length and the breadth of the rectangle so formed​

Answer 1

Step-by-step explanation:

Given

Perimeter of rectangular wire is 36 cm

So, let breadth of Wire be = x

Hence length of wire = x + 7

Perimeter of rectangle = (l+b)

(x + 7) + (x) = 36

x + 7 + x = 36

2x = 36 - 7

2x = 29

x = 29/2

x = 14.5

Therefore length of wire = x + 7 = 14.5 + 7 = 21.5cm

Breadth of wire = x = 14.5cm
