Area of Parallelograms, Triangles, & Trapezoids

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 5 cm and 7 cm, and a height of 4 cm, what is its area?

Back

Area = 1/2 * (5 + 7) * 4 = 24 cm²

Front

What is the area of a triangle with a base of 10 m and a height of 5 m?

Back

Area = 1/2 * 10 * 5 = 25 m²

Front

What is the area of a parallelogram with a base of 8 units and a height of 3 units?

Back

Area = 8 * 3 = 24 units²

Front

What is the area of a trapezoid with bases of 6 cm and 10 cm, and a height of 5 cm?

Back

Area = 1/2 * (6 + 10) * 5 = 40 cm²

Front

If a triangle has an area of 30 m² and a base of 12 m, what is its height?

Back

Height = (Area * 2) / Base = (30 * 2) / 12 = 5 m

Front

What is the area of a trapezoid with bases of 4 cm and 8 cm, and a height of 3 cm?

Back

Area = 1/2 * (4 + 8) * 3 = 18 cm²

Front

What is the area of a triangle with a base of 14 m and a height of 10 m?

Back

Area = 1/2 * 14 * 10 = 70 m²
