The length of a rectangle is 3 centimeters less than twice its width. The perimeter of the rectangle is 48 cm. What are the dimensions of the rectangle?

Respuesta :

l = 2w-3

perimeter = 2l +2w

48 = 2(2w-3) +2w

48 = 4w-6 +2w

48 = 6w-6

54 = 6w

w = 54/6 = 9

 width = 9

 length = 2(9)-3 = 18-3 = 15


Answer:

length=15,width=9
