The actual width (w) of a rectangle is 18 centimeters (cm). Use the scale drawing of the rectangle to find the actual length (l).
Answer: 54 cm
Explanation
The scale factor can be found by dividing the actual width by the width in the scale drawing. Actual width = 18 cm, scale width = 1.2 cm. Scale factor = Actual width / Scale width = 18 / 1.2 = 15.
The length in the scale drawing is 3.6 cm. Actual length = Scale length * Scale factor = 3.6 * 15 = 54 cm.
