Question

The area of the triangle below is 7.15 square centimeters. What is the length of the base?

Answer 1

The area of a triangle is given by:

`A=(1)/(2)bh`

where b is the base and h is the height. In this case we know that the area is 7.15 square cm and the height is 2.6 cm; plugging these values and solving for b we have:

`\begin{gathered} 7.15=(1)/(2)(2.6)b \\ b=(14.3)/(2.6) \\ b=5.5 \end{gathered}`

Therefore, the base is 5.5 cm
