Area of Triangles, Trapezoids, and Parallelograms

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.

Front

How do you calculate the area of a trapezoid?

Back

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

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

What units are used to measure area?

Back

Area is measured in square units, such as square feet (ft²), square meters (m²), or square centimeters (cm²).

Front

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

Back

Area = 1/2 * base * height = 1/2 * 10 ft * 5 ft = 25 ft².

Front

What is the area of a triangle with a base of 8 units and a height of 3 units?

Back

Area = 1/2 * base * height = 1/2 * 8 units * 3 units = 12 units².

Front

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

Back

Rearrange the area formula: height = (Area * 2) / base.

Front

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

Back

Area = 1/2 * (base1 + base2) * height = 1/2 * (6 cm + 10 cm) * 4 cm = 32 cm².

Front

If a parallelogram has a base of 12 m and a height of 5 m, what is its area?

Back

Area = base * height = 12 m * 5 m = 60 m².

Front

What is the relationship between the area of a triangle and the area of a parallelogram with the same base and height?

Back

The area of a triangle is half the area of a parallelogram with the same base and height.
