Area of Triangles 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 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 trapezoid has bases of 4 m and 8 m, and a height of 3 m, what is its area?

Back

Area = 1/2 × (4 m + 8 m) × 3 m = 18 m²

Front

What is the area of a triangle with a base of 12 m and a height of 4 m?

Back

Area = 1/2 × 12 m × 4 m = 24 m²

Front

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

Back

Area = 1/2 × (6 ft + 10 ft) × 5 ft = 40 ft²

Front

What is the area of a triangle with a base of 8 cm and a height of 3 cm?

Back

Area = 1/2 × 8 cm × 3 cm = 12 cm²

Front

What is the area of a trapezoid with bases of 5 cm and 15 cm, and a height of 10 cm?

Back

Area = 1/2 × (5 cm + 15 cm) × 10 cm = 100 cm²

Front

What is the area of a triangle with a base of 14 m and a height of 7 m?

Back

Area = 1/2 × 14 m × 7 m = 49 m²

Front

What is the area of a trapezoid with bases of 3 in and 7 in, and a height of 4 in?

Back

Area = 1/2 × (3 in + 7 in) × 4 in = 20 in²
