Area of parallelograms, triangles, and trapezoids 2

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base (b) × height (h)

Front

What is the formula for the area of a parallelogram?

Back

Area = base (b) × height (h)

Front

What is the formula for the area of a trapezoid?

Back

Area = 1/2 × (base1 + base2) × height (h)

Front

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

Back

Area = 1/2 × 10 m × 5 m = 25 m²

Front

A parallelogram has a base of 30 m and a height of 25 m. What is its area?

Back

Area = 30 m × 25 m = 750 m²

Front

What is the area of a trapezoid with bases of 8 m and 12 m, and a height of 5 m?

Back

Area = 1/2 × (8 m + 12 m) × 5 m = 50 m²

Front

How do you find the height of a triangle if you know the area and the base?

Back

Height = (2 × Area) / base (b)
