We are asked to use trigonometric ratios to find the diagonal of a square whose area is 49 square feet.
Explanation
The area of a square is given by the formula below.
[tex]\begin{gathered} Area\text{ = lenght}\times length=49 \\ l^2=49 \\ l=\sqrt{49} \\ l=7 \end{gathered}[/tex]Therefore, we can then draw an image of the square below.
