Area of Parallelograms

Front

What is the formula to calculate the area of a parallelogram?

Back

Area = base × height

Front

What is the base of a parallelogram?

Back

The base is one of the sides of the parallelogram on which it stands.

Front

What is the height of a parallelogram?

Back

The height is the perpendicular distance from the base to the opposite side.

Front

If the base of a parallelogram is 15 in. and the height is 9 in., what is the area?

Back

Area = 15 in. × 9 in. = 135 in²

Front

What is the area of a parallelogram with a base of 10 m and a height of 5 m?

Back

Area = 10 m × 5 m = 50 m²

Front

In a parallelogram, if the base is doubled and the height remains the same, what happens to the area?

Back

The area also doubles.

Front

What is the area of a parallelogram with a base of 20 cm and a height of 4 cm?

Back

Area = 20 cm × 4 cm = 80 cm²

Front

If a parallelogram has an area of 200 m² and a base of 10 m, what is the height?

Back

Height = Area ÷ base = 200 m² ÷ 10 m = 20 m

Front

What is the relationship between the area of a parallelogram and its opposite sides?

Back

The area is the same regardless of which side is considered the base.

Front

How does changing the height of a parallelogram affect its area?

Back

Increasing the height increases the area, while decreasing the height decreases the area.
