The length of a rectangle is five times the width. The area of the rectangle is 1620cm2. Work out the width of the rectangle.

For this question, we need to know the formula for finding the area of a rectangle is (length * width)From the question, Width = w; Length = 5wArea = 5w *w =1620cm2. therefore, 5w2 = 1620cm2. Divide both sides by 5w2 = 324. Take the square root of both sides w= 18
