Front

What is the formula for the area of a parallelogram?

Back

Area = base × height

Front

What is 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 the base of a parallelogram is 10 cm and the height is 5 cm, what is the area?

Back

Area = 10 cm × 5 cm = 50 cm²

Front

What is the area of a rectangle with a length of 8 m and a width of 3 m?

Back

Area = 8 m × 3 m = 24 m²

Front

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

Back

Height = (Area × 2) / base

Front

What is the area of a square with a side length of 4 cm?

Back

Area = 4 cm × 4 cm = 16 cm²

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 parallelogram with a base of 12 in and a height of 3 in?

Back

Area = 12 in × 3 in = 36 in²

Front

If the area of a triangle is 30 ft² and the base is 10 ft, what is the height?

Back

Height = (30 ft² × 2) / 10 ft = 6 ft
