Question

You are making a triangle-shaped pennant out of fabric. The base of the pennant is 5 inches and the height is 13 inches. How many fabric do you need to make the pennant?

Answer 1

32.5 inches squared of fabric

Answer 2

`\text{Area}=32.5in^2`

Step-by-step explanation

the area of a triangle is given by:

`\text{Area}=(base\cdot heigth)/(2)`

the, to know the fabric you need, you need to finde the area

Let

base=5 in

heigth=13 inches

now, replace.

`\begin{gathered} \text{Area}=(base\cdot heigth)/(2) \\ \text{Area}=\frac{5\text{ in}\cdot13\text{ in}}{2} \\ \text{Area}=(65in^2)/(2) \\ \text{Area}=32.5in^2 \end{gathered}`

I hope this helps you
