Area of Trapezoids, Triangles and Parallelograms

Front

What is the formula for the area of a trapezoid?

Back

Area = (1/2) × (Base1 + Base2) × Height

Front

What is the formula for the area of a triangle?

Back

Area = (1/2) × Base × Height

Front

What is the formula for the area of a parallelogram?

Back

Area = Base × Height

Front

If a trapezoid has bases of 10m and 6m, and a height of 4m, what is its area?

Back

Area = (1/2) × (10 + 6) × 4 = 32 m²

Front

A triangle has a base of 5m and a height of 12m. What is its area?

Back

Area = (1/2) × 5 × 12 = 30 m²

Front

A parallelogram has a base of 8m and a height of 3m. What is its area?

Back

Area = 8 × 3 = 24 m²

Front

What is the area of a triangle with a base of 9m and a height of 4m?

Back

Area = (1/2) × 9 × 4 = 18 m²

Front

If the area of a parallelogram is 50 in² and the base is 10 in, what is the height?

Back

Height = Area / Base = 50 / 10 = 5 in

Front

What is the area of a trapezoid with bases of 12m and 8m, and a height of 5m?

Back

Area = (1/2) × (12 + 8) × 5 = 50 m²

Front

A triangle has an area of 24 m² and a base of 6m. What is the height?

Back

Height = (2 × Area) / Base = (2 × 24) / 6 = 8 m
