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 the base of a parallelogram is 10 inches and the height is 5 inches, what is the area?

Back

Area = 10 inches × 5 inches = 50 square inches

Front

If the base of a triangle is 8 feet and the height is 6 feet, what is the area?

Back

Area = (8 feet × 6 feet) / 2 = 24 square feet

Front

What is the area of a parallelogram with a base of 12 cm and a height of 4 cm?

Back

Area = 12 cm × 4 cm = 48 cm²

Front

What is the area of a triangle with a base of 10 m and a height of 5 m?

Back

Area = (10 m × 5 m) / 2 = 25 m²

Front

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

Back

Height = Area / base

Front

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

Back

Base = (Area × 2) / height

Front

What is the area of a triangle with a base of 14 inches and a height of 3 inches?

Back

Area = (14 inches × 3 inches) / 2 = 21 inches²

Front

If a parallelogram has an area of 72 square feet and a base of 9 feet, what is the height?

Back

Height = 72 square feet / 9 feet = 8 feet
