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 parallelogram?

Back

Area = base × height

Front

If a triangle has a base of 10 ft and a height of 6 ft, what is its area?

Back

Area = 1/2 × 10 ft × 6 ft = 30 ft²

Front

If a parallelogram has a base of 8 ft and a height of 5 ft, what is its area?

Back

Area = 8 ft × 5 ft = 40 ft²

Front

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

Back

Area = 1/2 × 12 in × 4 in = 24 in²

Front

What is the area of a parallelogram with a base of 10 m and a height of 3 m?

Back

Area = 10 m × 3 m = 30 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 triangle with a base of 5 cm and a height of 10 cm?

Back

Area = 1/2 × 5 cm × 10 cm = 25 cm²

Front

What is the area of a parallelogram with a base of 6 ft and a height of 7 ft?

Back

Area = 6 ft × 7 ft = 42 ft²

Front

If the area of a triangle is 36 ft² and the base is 12 ft, what is the height?

Back

Height = (36 ft² × 2) / 12 ft = 6 ft
