Area of Parallelograms and Triangles

Front

What is the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: Area = Base (B) × Height (H).

Front

What is the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × Base (B) × Height (H).

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = Length × Width.

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 inches (in²).

Front

If the base of a parallelogram is 5 units and the height is 4 units, what is the area?

Back

Area = Base × Height = 5 units × 4 units = 20 units².

Front

What is the area of a rectangle with a length of 10 feet and a width of 4 feet?

Back

Area = Length × Width = 10 ft × 4 ft = 40 ft².

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 triangle with a base of 6 units and a height of 3 units?

Back

Area = 1/2 × Base × Height = 1/2 × 6 units × 3 units = 9 units².

Front

What is the area of a parallelogram with a base of 8 cm and a height of 5 cm?

Back

Area = Base × Height = 8 cm × 5 cm = 40 cm².

Front

What is the area of a triangle with a base of 10 units and an area of 20 units²?

Back

To find the height, use: Height = (Area × 2) / Base = (20 units² × 2) / 10 units = 4 units.
