Area of Parallelograms and Triangles

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 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

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 area of a rectangle?

Back

Area = length × width

Front

If a rectangle has a length of 4 m and a width of 3 m, what is its area?

Back

Area = 4 m × 3 m = 12 m²

Front

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

Back

Area = 6 cm × 4 cm = 24 cm²

Front

What is the area of a triangle with a base of 12 ft and a height of 5 ft?

Back

Area = 1/2 × 12 ft × 5 ft = 30 ft²

Front

What is the area of a parallelogram with a base of 10 in and a height of 5 in?

Back

Area = 10 in × 5 in = 50 in²

Front

If the area of a triangle is 20 units² and the base is 8 units, what is the height?

Back

Height = (Area × 2) / base = (20 units² × 2) / 8 units = 5 units
