Area of parallelograms, triangles, and trapezoids 2

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height

Front

How do you calculate the area of a triangle?

Back

Area = (base × height) / 2

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 m and the height is 5 m, what is the area?

Back

Area = (10 m × 5 m) / 2 = 25 m²

Front

What is the area of a parallelogram with a base of 8 ft and a height of 4 ft?

Back

Area = 8 ft × 4 ft = 32 ft²

Front

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

Back

Area = (1/2) × (6 m + 10 m) × 4 m = 32 m²

Front

What is the area of a triangle with a base of 12 units and a height of 3 units?

Back

Area = (12 units × 3 units) / 2 = 18 units²

Front

If the area of a parallelogram is 50 m² and the base is 10 m, what is the height?

Back

Height = Area / base = 50 m² / 10 m = 5 m

Front

What is the area of a triangle with a base of 8 cm and a height of 6 cm?

Back

Area = (8 cm × 6 cm) / 2 = 24 cm²

Front

If a trapezoid has an area of 40 m², base1 of 8 m, and base2 of 12 m, what is the height?

Back

Height = (Area × 2) / (base1 + base2) = (40 m² × 2) / (8 m + 12 m) = 4 m
