Answer:
6.6 ft
Step-by-step explanation:
The area of a triangle is given by the formula: [tex]A=\frac{1}{2}bh[/tex].
In this case, the base b equals the height h.
[tex]\therefore A=\frac{1}{2}h^2 \rightarrow h=\sqrt{2A}[/tex]
Given: A = 22 ft²
[tex]\therefore h=\sqrt{2A} = \sqrt{2(22 \text{ ft}^2)} = \sqrt{44}\text{ ft} \approx 6.6 \text{ ft}[/tex]
