Area of Triangles and Parallelograms

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 cm and a height of 5 cm, what is its area?

Back

Area = 1/2 × 10 cm × 5 cm = 25 cm²

Front

What is the area of a triangle with a base of 8 m and a height of 3 m?

Back

Area = 1/2 × 8 m × 3 m = 12 m²

Front

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

Back

Height = (Area × 2) / base

Front

What is the area of a parallelogram with a base of 6 m and a height of 4 m?

Back

Area = 6 m × 4 m = 24 m²

Front

If the area of a triangle is 30 cm² and the base is 10 cm, what is the height?

Back

Height = (30 cm² × 2) / 10 cm = 6 cm

Front

What is the area of a triangle with all sides measuring 5 cm?

Back

Area = 1/2 × base × height; height can be calculated using Pythagorean theorem.

Front

What is the relationship between the area of a triangle and the area of a parallelogram with the same base and height?

Back

The area of the triangle is half the area of the parallelogram.

Front

What units are used to measure area?

Back

Square units (e.g., cm², m², km², in²)
