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
