Answer:
99
Step-by-step explanation:
area of a triangle formula = [tex]\frac{bh}{2}[/tex]
where b = base length and h = height
The triangle shown has a base length of 11 and a height of 18
Using this information we plug in the values into the formula
[tex]A=\frac{11*18}{2} \\11*18=198\\\frac{198}{2} =99[/tex]
Hence the area of the triangle is 99ft²
