Area of Parallelograms and Triangles

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height

Front

What is the formula for the area of a triangle?

Back

Area = (base × height) / 2

Front

If a parallelogram has a base of 10 cm and a height of 5 cm, what is its area?

Back

Area = 10 cm × 5 cm = 50 cm²

Front

If a triangle has a base of 8 mm and a height of 3 mm, what is its area?

Back

Area = (8 mm × 3 mm) / 2 = 12 mm²

Front

What is the area of a rectangle with a length of 4 cm and a width of 3 cm?

Back

Area = length × width = 4 cm × 3 cm = 12 cm²

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 10 ft and a height of 5 ft?

Back

Area = (10 ft × 5 ft) / 2 = 25 ft²

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 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.
