The given figure is triangle with a 90 degree
The general expression for the area of triangle = 1/2 x Base x Height
In the given figure :
Height = 26.4 ft
Base = 11 ft
Substitute the value of Height and Base in the expression for tha area of triangle :
[tex]\begin{gathered} \text{ Area of triangle = }\frac{1}{2}\times26.4\times11 \\ \text{ Area of triangle = }145.20ft^2 \end{gathered}[/tex]Area of the triangle is 145.20 ft²
