Hello!
To calculate the area of a triangle, we must use the formula below:
[tex]\mathrm{Area=\dfrac{base\times height}{2}}[/tex]In this triangle, we have:
• base,: 6 feet
,• height,: 10 feet
Knowing it, let's replace the formula with the values:
[tex]\mathrm{Area=\dfrac{6\times10}{2}}=\frac{60}{2}=30\text{ }\mathrm{feet^2}[/tex]A. 30 square feet
