Area of Rectangles and Parallelograms

Front

What is the formula for calculating the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

What is the formula for calculating the area of a parallelogram?

Back

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

Front

If a rectangle has a length of 10 m and a width of 5 m, what is its area?

Back

The area of the rectangle is 50 square meters (10 m × 5 m = 50 m²).

Front

What is the relationship between the base and height in the area formula for a parallelogram?

Back

In the area formula for a parallelogram, the base and height are perpendicular to each other; the height is the vertical distance from the base to the opposite side.

Front

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

Back

To find the height of a parallelogram, use the formula: height = Area ÷ base.

Front

What is the area of a rectangle with a length of 12 ft and a width of 8 ft?

Back

The area of the rectangle is 96 square feet (12 ft × 8 ft = 96 ft²).

Front

If the area of a parallelogram is 50 cm² and the base is 10 cm, what is the height?

Back

The height of the parallelogram is 5 cm (height = Area ÷ base = 50 cm² ÷ 10 cm).

Front

What units are used to measure area?

Back

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

Front

What is the area of a rectangle with a length of 15 m and a width of 10 m?

Back

The area of the rectangle is 150 square meters (15 m × 10 m = 150 m²).

Front

How do you calculate the area of a rectangle if only the area and one dimension is known?

Back

If the area and one dimension (length or width) are known, you can find the other dimension using: other dimension = Area ÷ known dimension.
