Area of rectangular window is 360 square centimeters if the length of the window is bigger than the width of the window by 4 centimeters what are the dimensions

The area of a rectangle has a formula of

A = LW

where L is the length and W is the width of the rectangle. Since it is mentioned in the problem that the length is bigger than the width by 4 cm,

L = 4 + W

Substituting this to the area formula:

360 cm² = (4 + W) (W)

Solving for W,

W = 17.08,-21.08

Since it is a quadratic formula, there are two roots. We use the positive root as the answer. So, W = 17.08 cm. Then,

L = 4 + 17.08 = 21.08 cm

Thus, the dimensions of the rectangle are 21.08 cm long and 17.08 cm wide.
