Given:

it is given that the perimeter of a rectangle is 64 cm. The length is 7

less than 2 times the width.

Find:

we have to find the width of the rectangle

Explanation:

we know the perimeter of a rectangle = 2*length + 2* width

let x be the width of the rectangle,

then 2x - 7 is the length of the rectangle.

Therefore, we have

64 = 2(2x - 7) + 2x

64 = 4x - 14 + 2x

64 + 14 = 6x

6x = 78

x = 78/6

x = 13 cm

Therefore, width of the rectangle is 13 cm
