Step-by-step explanation: Step 1: Work out the missing lengths around the edge of the compound shape. Step 2: Divide your L shape into two rectangles. ... Do this by multiplying the base of the rectangle by the height of the rectangle. Step 4: Add the areas of the rectangles together to give the total area of the L shape.
So the total area of the compound shape is 48 cm². Summary: Find the missing lengths around your L shape and divide the shape into 2 rectangles. Find the area of both rectangle and add them up to give the total area of the compound shape.
