Looking at the figure, we see that there are 6 identical squares of side 26 yd.
We know that the area of a square of side L can be calculated using the formula:
[tex]A=L^2[/tex]Now, if there are 6 squares, the total area is:
[tex]A_{\text{Total}}=6\cdot L^2[/tex]From the problem, L = 26 yd, then:
[tex]\begin{gathered} A_{\text{total}}=6\cdot26^2 \\ \therefore A_{Total}=4056yd^2 \end{gathered}[/tex]
