Question

5. A triangle has base 15 ft and area 60 ft? What is the height? A = 1/2 BH

Answer 1

Given:

Base of triangle, b = 15 ft

Area of triangle, A = 60 ft

Height of triangle, h = ??

To find the height, use the area of a triangle formula below:

`A\text{ = }(1)/(2)bh`

Substitute values in the formula:

`60=(1)/(2)\ast15\ast h`

Solving further, we have:

`\begin{gathered} 60\text{ = 7.5h} \\ \text{Divide both sides by 7.5} \\ \\ (60)/(7.5)=(7.5h)/(7.5) \\ \\ 8\text{ = h} \end{gathered}`

Therefore the height of the triangle is 8 feet

ANSWER:

8 ft
