Area of a Triangle

Front

What is the area of a triangle?

Back

The area of a triangle is the amount of space inside the triangle, measured in square units.

Front

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

Back

A = 1/2 bh, where 'b' is the base and 'h' is the height.

Front

If the base of a triangle is 10 inches and the height is 6 inches, what is the area?

Back

A = 1/2 * 10 * 6 = 30 square inches.

Front

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

Back

Area is measured in square units, such as square inches (in²), square centimeters (cm²), etc.

Front

If a triangle has an area of 48 in² and a base of 12 inches, what is the height?

Back

Using the formula A = 1/2 bh, we can rearrange it to find h: h = 2A/b. So, h = 2*48/12 = 8 inches.

Front

What does 'base' refer to in a triangle?

Back

The base is one side of the triangle, often the bottom side, used to calculate the area.

Front

What does 'height' refer to in a triangle?

Back

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

Front

If a triangle has a base of 8 cm and a height of 5 cm, what is its area?

Back

A = 1/2 * 8 * 5 = 20 cm².

Front

What is the area of a triangle with a base of 14 inches and a height of 4 inches?

Back

A = 1/2 * 14 * 4 = 28 square inches.

Front

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

Back

You can rearrange the formula A = 1/2 bh to find height: h = 2A/b.
