Area of Parallelograms, Triangles, & Trapezoids

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 = 1/2 × base × height

Front

What is the formula for the area of a trapezoid?

Back

Area = 1/2 × (base1 + base2) × height

Front

What does 'area' mean in geometry?

Back

The amount of space inside a shape.

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

If a parallelogram has a base of 8 m and a height of 3 m, what is its area?

Back

Area = 8 m × 3 m = 24 m²

Front

What is the area of a trapezoid with bases of 6 m and 10 m, and a height of 4 m?

Back

Area = 1/2 × (6 m + 10 m) × 4 m = 32 m²

Front

How do you find the area of a rectangle?

Back

Area = length × width

Front

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

Back

Area = 1/2 × 12 in × 4 in = 24 in²

Front

If a trapezoid has an area of 50 cm² and a height of 5 cm, what is the average of the bases?

Back

Average of bases = Area / height × 2 = 50 cm² / 5 cm × 2 = 20 cm
