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

How do you find the height of a trapezoid if you know the area and the bases?

Back

Height = (2 × Area) / (Base1 + Base2)

Front

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

Back

Area = (1/2) × 10 ft × 5 ft = 25 ft²

Front

If a parallelogram has a base of 8 m and a height of 3 m, what is its area?

Back

Area = 8 m × 3 m = 24 m²

Front

What is the area of a trapezoid with bases of 6 in and 10 in, and a height of 4 in?

Back

Area = (1/2) × (6 in + 10 in) × 4 in = 32 in²

Front

If the area of a triangle is 30 ft² and the base is 10 ft, what is the height?

Back

Height = (2 × Area) / Base = (2 × 30 ft²) / 10 ft = 6 ft

Front

What is the area of a parallelogram with a base of 12 cm and a height of 5 cm?

Back

Area = 12 cm × 5 cm = 60 cm²

Front

How do you calculate the area of a trapezoid with unequal bases?

Back

Use the formula: Area = (1/2) × (Base1 + Base2) × Height.
