If a composite figure consists of a rectangle (10 cm by 4 cm) and a triangle (base 4 cm, height 3 cm), what is the total area?

Back

Area of rectangle = 10 cm × 4 cm = 40 cm²; Area of triangle = 1/2 × 4 cm × 3 cm = 6 cm²; Total area = 40 cm² + 6 cm² = 46 cm².

What is the area of a shaded region if the total area is 350 cm² and the unshaded area is 137.5 cm²?

Back

Shaded area = Total area - Unshaded area = 350 cm² - 137.5 cm² = 212.5 cm².
