Area of a triangle, Trapezoid, and Parallelogram

Front

What is the formula to find the area of a triangle?

Back

Area = 1/2 × base × height

Front

What is the formula to find the area of a trapezoid?

Back

Area = 1/2 × (base1 + base2) × height

Front

What is the formula to find the area of a parallelogram?

Back

Area = base × height

Front

If the base of a triangle is 10 cm and the height is 5 cm, what is the area?

Back

Area = 1/2 × 10 cm × 5 cm = 25 cm²

Front

If a trapezoid has bases of 8 cm and 12 cm, and a height of 4 cm, what is the area?

Back

Area = 1/2 × (8 cm + 12 cm) × 4 cm = 40 cm²

Front

True or False: The area of a square can be found by squaring the length of one side.

Back

True

Front

What is the area of a parallelogram with a base of 6 m and a height of 3 m?

Back

Area = 6 m × 3 m = 18 m²

Front

If a trapezoid has bases of 5 cm and 15 cm, and a height of 10 cm, what is the area?

Back

Area = 1/2 × (5 cm + 15 cm) × 10 cm = 100 cm²

Front

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

Back

Area = 1/2 × 12 m × 4 m = 24 m²

Front

If the area of a parallelogram is 30 cm² and the base is 5 cm, what is the height?

Back

Height = Area / base = 30 cm² / 5 cm = 6 cm
