Area of a Triangle

Front

What is the formula for the area of a triangle?

Back

A = (b × h) / 2, where A is the area, b is the base, and h is the height.

Front

If the base of a triangle is 10 ft and the height is 12 ft, what is the area?

Back

A = (10 ft × 12 ft) / 2 = 60 ft².

Front

What units are used to measure the area of a triangle?

Back

Square units, such as square feet (ft²), square centimeters (cm²), or square inches (in²).

Front

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

Back

Rearrange the area formula: h = (2A) / b.

Front

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

Back

A = (5 cm × 8 cm) / 2 = 20 cm².

Front

What is the area of a triangle with a base of 15 in and a height of 4 in?

Back

A = (15 in × 4 in) / 2 = 30 in².

Front

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

Back

A = (6 m × 10 m) / 2 = 30 m².

Front

If a triangle has an area of 24 cm² and a base of 6 cm, what is the height?

Back

h = (2 × 24 cm²) / 6 cm = 8 cm.

Front

What is the area of a triangle with a base of 9 ft and a height of 3 ft?

Back

A = (9 ft × 3 ft) / 2 = 13.5 ft².

Front

How does changing the base of a triangle affect its area?

Back

Increasing the base while keeping the height constant increases the area, and vice versa.
