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 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 10 m and 6 m, and a height of 4 m, what is its area?

Back

Area = (1/2) × (10 + 6) × 4 = 32 m²

Front

What is the area of a triangle with a base of 8 cm and a height of 5 cm?

Back

Area = (1/2) × 8 × 5 = 20 cm²

Front

How do you find the height of a parallelogram if you know the area and base?

Back

Height = Area / Base

Front

What is the area of a parallelogram with a base of 12 m and a height of 10 m?

Back

Area = 12 × 10 = 120 m²

Front

If the area of a trapezoid is 36 m² and the height is 3 m, what is the average of the two bases?

Back

Average of bases = Area / Height = 36 / 3 = 12 m

Front

What is the area of a triangle with a base of 10 in and a height of 4 in?

Back

Area = (1/2) × 10 × 4 = 20 in²

Front

If a parallelogram has an area of 50 m² and a base of 5 m, what is the height?

Back

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