A rectangle has a width that is 7 centimeters less than its length, and its area is 330 square centimeters. What are
the dimensions of the rectangle?
length =
centimeters
width =
centimeters

w = 15 cm

l = 22 cm

Step-by-step explanation:

A = w·l

w = l - 7

A = (l - 7)·l

330 = l² - 7l

l² - 7l - 330 = 0

l² + 15l - 2l - 330 = 0

l(l + 15) - 22(l + 15) = 0

(l - 22)(l + 15) = 0

l - 22 = 0 => l = 22 cm

l + 15 = 0 => l = - 15 < 0 (f)

w = l - 7 = 22 - 7 => w = 15 cm
