5. B divide the shape into two pieces: One 2 inches wide and 9 inches long, and the other with 3 inches wide and 3 inches long. Find the area, and the result should be 18 inches and 9 inches; 18 + 9 = 27 squared inches. 6. D The same rule applies: Divide the shape into a rectangle 4cm wide and 12cm long, and a triangle with 3cm long and 4cm wide. This might be a bit confusing, but since there are two triangles, the division of two is not required. Anyways, the area of the rectangle is 48cm and the area of the triangle is 12 cm; 48 + 12 = 60 squared centimeters. 7. 80 squared centimeters. Using the same rule, you divide the shape into two trapezoids, and end up with the are of each being 46cm ((13 + 10) • 4/2) and 34cm ((10 + 7) • 4/2); 46 + 34 = 80 squared centimeters.
