Area of Parallelograms, Triangles, and Trapezoids

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 triangle?

Back

Area = (Base × Height) / 2

Front

What is the formula for the area of a trapezoid?

Back

Area = (Base1 + Base2) × Height / 2

Front

If the base of a parallelogram is 5 inches and the height is 3 inches, what is the area?

Back

Area = 5 inches × 3 inches = 15 inches²

Front

What does 'height' refer to in geometry?

Back

Height is the perpendicular distance from the base to the top of a shape.

Front

If a triangle has a base of 10 cm and a height of 4 cm, what is its area?

Back

Area = (10 cm × 4 cm) / 2 = 20 cm²

Front

What is the height of a trapezoid if the area is 30 in², Base1 is 6 in, and Base2 is 4 in?

Back

Height = (Area × 2) / (Base1 + Base2) = (30 in² × 2) / (6 in + 4 in) = 3 in

Front

What is the area of a parallelogram with a base of 8 m and a height of 5 m?

Back

Area = 8 m × 5 m = 40 m²

Front

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

Back

Area = (10 m + 6 m) × 4 m / 2 = 32 m²

Front

What is the area of a triangle with a base of 12 inches and a height of 5 inches?

Back

Area = (12 inches × 5 inches) / 2 = 30 inches²
