Area of Parallelograms, Triangles, and Trapezoids

Front

What is the formula for the area of a trapezoid?

Back

Area = (1/2) × (Base1 + Base2) × Height

Front

What is 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

How do you find the area of a trapezoid with bases of 5 cm and 7 cm and a height of 4 cm?

Back

Area = (1/2) × (5 + 7) × 4 = 24 cm²

Front

If a triangle has a base of 10 units and a height of 5 units, what is its area?

Back

Area = (1/2) × 10 × 5 = 25 units²

Front

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

Back

Area = 8 × 3 = 24 m²

Front

If a trapezoid has an area of 30 square cm and a height of 5 cm, what is the average of the bases?

Back

Average of bases = Area / Height = 30 / 5 = 6 cm

Front

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

Back

Area = (1/2) × 12 × 4 = 24 cm²

Front

How do you calculate the area of a trapezoid with bases of 6 m and 10 m and a height of 5 m?

Back

Area = (1/2) × (6 + 10) × 5 = 40 m²

Front

What is the area of a parallelogram with a base of 10 ft and a height of 6 ft?

Back

Area = 10 × 6 = 60 ft²
