Question

a piece of wire is 144cm long what will be the lenght of each side in a rectangle with breadth 34cm​

Answer 1

Answer:

Given,

Length of wire = 144 cm

Breadth, b = 34 cm

Let us assume that the length of wire be the perimeter of the rectangle.

∴ Perimeter = 2 (l + b)

             144 = 2 (l + 34)

             144 = 2l + 68

                2l = 144 - 68

                2l = 76

                  l = $\frac{76}{2}$

                  l = 38 cm
