Area Of A Triangle

Front

What is the formula to find the area of a triangle?

Back

The area of a triangle is given by the formula: \( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \)

Front

If a triangle has a base of 14 cm and a height of 23 cm, what is its area?

Back

The area is \( \frac{1}{2} \times 14 \times 23 = 161 \text{ cm}^2 \)

Front

What do you need to know to find the area of a triangle?

Back

You need to know the base and height of the triangle.

Front

Which expression correctly calculates the area of a triangle with base 10 and height 12?

Back

The correct expression is \( \frac{10 \times 12}{2} \) which equals 60.

Front

What is the area of a triangle with base 8 and height 12?

Back

The area is \( \frac{1}{2} \times 8 \times 12 = 48 \text{ units}^2 \)

Front

What is the unit of measurement for area?

Back

The unit of measurement for area is square units, such as cm² or in².

Front

If a triangle has an area of 24 in² and a base of 8 in, what is its height?

Back

Using the formula \( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \), the height is 6 in.

Front

What is the height of a triangle if the area is 30 cm² and the base is 10 cm?

Back

The height is 6 cm, calculated using \( \text{Area} = \frac{1}{2} \times 10 \times \text{height} \).

Front

Which numbers do we not need to find the area of a triangle?

Back

We do not need the lengths of the two equal sides if we have the base and height.

Front

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

Back

The area is \( \frac{1}{2} \times 5 \times 10 = 25 \text{ m}^2 \)
