Front

What is the area formula for a trapezoid?

Back

Area = (1/2) × (Base1 + Base2) × Height

Front

What is the area of a trapezoid with bases 5 cm and 7 cm, and height 3 cm?

Back

Area = (1/2) × (5 + 7) × 3 = 18 cm²

Front

What is the area of a trapezoid with bases 10 m and 14 m, and height 4 m?

Back

Area = (1/2) × (10 + 14) × 4 = 48 m²
