Question

I need help figuring out the answer to the inches

Answer 1

Given:

The dimensions of the triangular pennant:

height = 17.4 in

Area = 82.65 square inch

Le the measure of the base be x

The area (A), height (h) and base (b) of a triangle are related by the formula:

`A\text{ = }(1)/(2)\text{ b }*\text{ h}`

Substituting the given values:

`\begin{gathered} 82.65\text{ = }(1)/(2)\text{ }*\text{ x }*\text{ 17.4} \\ Cross-Multiply \\ 17.4x\text{ = 165.3} \\ x\text{ = 9.5} \end{gathered}`

Hence, the measure of the base is 9.5 in
