To answer this question, we need to remember the formula for finding the area of a triangle:

[tex]A_{\text{triangle}}=\frac{b\cdot h}{2}[/tex]

Where

• b is the base of the triangle

,

• h is the height of the triangle

Then, we have that:

b = 5ft

h = 8.4ft

Then, we have:

[tex]A_{\text{triangle}}=\frac{5ft\cdot8.4ft}{2}=\frac{42ft^2}{2}\Rightarrow A_{triangle}=21ft^2[/tex]

Therefore, the area of this triangle is equal to 21 sq. feet.
