Area of parallelograms, triangles, and trapezoids 2

Front

What is the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × base × height.

Front

What is the area of a trapezoid?

Back

The area of a trapezoid is calculated using the formula: Area = 1/2 × (base1 + base2) × height.

Front

Calculate the area of a triangle with a base of 5 units and a height of 4 units.

Back

Area = 1/2 × 5 × 4 = 10 units².

Front

Calculate the area of a trapezoid with bases of 6 units and 10 units, and a height of 5 units.

Back

Area = 1/2 × (6 + 10) × 5 = 40 units².

Front

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: Area = base × height.

Front

Calculate the area of a parallelogram with a base of 8 units and a height of 3 units.

Back

Area = 8 × 3 = 24 units².

Front

If the area of a triangle is 20 units² and the base is 5 units, what is the height?

Back

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

Front

If the area of a trapezoid is 50 units² and the height is 5 units, what is the average of the bases?

Back

Average of bases = Area / height × 2 = 50 / 5 × 2 = 20 units.

Front

What is the area of a triangle with a base of 10 units and a height of 6 units?

Back

Area = 1/2 × 10 × 6 = 30 units².

Front

What is the area of a trapezoid with bases of 4 units and 8 units, and a height of 3 units?

Back

Area = 1/2 × (4 + 8) × 3 = 18 units².
