Question

a wire of length 86 cm is bent in the form of a rectangle such that it's length is 7 cm more than it's breadth of the rectangle so formed.​

Answer 1

Step-by-step explanation:

Let the breadth be x.

∴ Length = x + 7

Perimeter of wire = 86

2(1+b) = 86

⇒l+b=86/2

⇒l+b=43

⇒x+7+x=43

⇒ 2x=43-7

⇒2x=36

⇒x=18

∴ Length = x + 7 = 18 + 7 = 25 cm
