Interactive practice questions
Find the shaded area of the figure shown.
A blue-shaded composite figure is formed by a rectangle with two identical right-angled triangles removed from the top-right and bottom-left corners. The bottom side of the composite figure measures $11$11 units as indicated by a horizontal dimension line. The right side of the composite figure measures $5$5 units as indicated by a vertical dimension line. The cut-out identical triangles are outlined in dashed lines. The horizontal side of each triangle, which is also the base, is marked with a double tick mark. The vertical side of each triangle, which is also the height, is marked with a single tick mark. The right vertical side of the top-right triangle measures $6$6 units. The bottom horizontal side of the bottom-left triangle measures $10$10 units. The right angle of each triangle is marked with a small green-shaded square.
