To find the area of the triangle, we will use the formula below:
[tex]A=\text{ }\frac{1}{2}\times b\times h[/tex]where b is the base
h is the height
A is the area of the triangle
From the question,
b = 10 and h = 6
substitute the value into the formula and evaluate
[tex]A=\text{ }\frac{1}{2}\times10\times6[/tex][tex]=30ft^2[/tex]
