Area: Parallelograms, Trapezoids, and Triangles

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 a triangle has a base of 10 cm and a height of 5 cm, what is its area?

Back

Area = 1/2 × 10 cm × 5 cm = 25 cm²

Front

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

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 cm and a height of 6 cm?

Back

Area = 1/2 × 12 cm × 6 cm = 36 cm²

Front

What is the area of a parallelogram with a base of 5 m and a height of 3 m?

Back

Area = 5 m × 3 m = 15 m²

Front

What is the area of a trapezoid with bases of 4 ft and 8 ft, and a height of 5 ft?

Back

Area = 1/2 × (4 ft + 8 ft) × 5 ft = 30 ft²

Front

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

Back

Area = 1/2 × 14 cm × 10 cm = 70 cm²
