HELP ASP PLS I WILL GOVE BRAINIST PLS PLS PLS HELPPPP picture below

We can solve this problem in three steps.
1) find the area of the square
[tex]a=lw\\\\a=(7.5)(6)\\\\a=45ft^{2}[/tex]
2) find the area of the triangle
[tex]a=\frac{1}{2}bh\\\\a=\frac{1}{2} (6)(4)\\\\a=12ft^{2}[/tex]
3) add the areas together
[tex]a=45+12[/tex]
a = 57 ft²
