find the total area of the given figure

Answer:
[tex]A=996\ in^2[/tex]
Step-by-step explanation:
we know that
The total area of the figure is equal to the area of the square plus the area of the triangle
step 1
Find the area of triangle
The area of triangle is equal to
[tex]A=\frac{1}{2}(b)(h)[/tex]
where
b is the base of triangle (is the same that the length side of the square)
h is the height of triangle
we have
[tex]h=35\ in[/tex]
Applying the Pythagorean Theorem
Find the length side b
[tex]37^2=35^2+(b/2)^2[/tex]
[tex](b/2)^2=37^2-35^2[/tex]
[tex](b/2)^2=144[/tex]
[tex](b/2)=12\\b=24\ in[/tex]
Area of triangle
[tex]A=\frac{1}{2}(24)(35)=420\ in^2[/tex]
step 2
Find the area of the square
The area of the square is
[tex]A=b^2[/tex]
we have
[tex]b=24\ in[/tex]
substitute
[tex]A=(24)^2=576\ in^2[/tex]
step 3
Find the total area of the figure
Adds the areas
[tex]A=420+576=996\ in^2[/tex]
