The diagram shows an L-shaped courtyard. Every corner is a right angle, and all side lengths are in meters.
Draw the split on the courtyard. Use separate paper for your equation.
Split the courtyard into two nonoverlapping rectangles. Write an addition equation using the two rectangle areas, then find the total area in square meters.
