Question

find its length and breadth.
5. A wire of length 86 cm is bent in the form of a rectangle such that its length is 7 cm mores
Find the length and breadth of the rectangle so formed.​

Answer 1

Answer:

Length of the rectangle = 25 cm

Breadth of the rectangle = 18 cm

Step-by-step explanation:

Since a wire of Length 86 cm is bent in the form of a rectangle,

Therefore perimeter of the rectangle = 86 cm.

Let the breadth of the rectangle be 'x' cm

Therefore by the given problem, length = 'x + 7' cm.

So, 2( Length + Breadth) = 86 cm.

i.e, 2( x + 7 + x) = 86 cm

= 2(2x + 7) = 86 cm

= (2x + 7) = 86/2

= 2x + 7 = 43

= 2x = 43 - 7

= 2x = 36

= x = 18

Therefore, Breadth = 18 cm

& Length = 18 + 7 = 25 cm
