Question: 1 / 400

If a triangle has an area of 30 cm² and a base of 6 cm, what is its height?

5 cm

6 cm

10 cm

To determine the height of a triangle given its area and base, you can use the formula for the area of a triangle:

Area = (Base × Height) / 2

In this case, the area is 30 cm² and the base is 6 cm. Plugging these values into the formula, we have:

30 = (6 × Height) / 2

To eliminate the fraction, multiply both sides by 2:

60 = 6 × Height

Next, divide both sides by 6 to solve for Height:

Height = 60 / 6 = 10 cm

Therefore, the height of the triangle is 10 cm, making the correct answer the option that states that height is 10 cm. This calculation illustrates how to manipulate the area formula to find an unknown dimension (height) when the area and base are known.
