Question

The diagram show the outline of the triangular foundation of a front porch.A triangle is with base labeled fifteen and five tenths feet and height is labeled twelve feet.What is the area of the foundation?

Answer 1

13.75 square feet

Explanation:

Given:

Base = 15.5 feet

Height = 12 feet

Since it has the shape of a triangle, the area of the triangle is given by the following formula:

`A=(b\cdot h)/(2)`

We replacing:

`\begin{gathered} A=(15.5+12)/(2) \\ A=(27.5)/(2) \\ A=13.75in^2 \end{gathered}`

the area of the foundation is 13.75 square feet
