Area of Triangles, Parallelograms and Trapezoids

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

What is the formula for the area of a trapezoid?

Back

Area = 1/2 × (base1 + base2) × height

Front

If the base of a triangle is 10 cm and the height is 5 cm, what is the area?

Back

Area = 1/2 × 10 cm × 5 cm = 25 cm²

Front

If a parallelogram has a base of 8 m and a height of 4 m, what is its area?

Back

Area = 8 m × 4 m = 32 m²

Front

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

Back

Area = 1/2 × (6 m + 10 m) × 5 m = 40 m²

Front

What is the area of a triangle with a base of 12 yd and a height of 10 yd?

Back

Area = 1/2 × 12 yd × 10 yd = 60 yd²

Front

If a parallelogram has an area of 48 m² and a height of 6 m, what is the base?

Back

Base = Area / height = 48 m² / 6 m = 8 m

Front

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

Back

Area = 1/2 × (4 in + 8 in) × 3 in = 18 in²

Front

If a triangle has an area of 30 cm² and a base of 10 cm, what is the height?

Back

Height = 2 × Area / base = 2 × 30 cm² / 10 cm = 6 cm
