Answer:

$40\ in^(2)$

Explanation:

we know that

The area of the composite figure is equal to the area of a rectangle plus the area of a triangle

Find the area of the rectangle

A1=bh

we have

$b=5\ in\\h=7\ in$

substitute

$A1=5*7=35\ in^(2)$

Find the area of the triangle

A2=bh/2

we have

$b=5-3=2\ in\\h=12-7=5\ in$

substitute

$A2=2*5/2=5\ in^(2)$

Adds the areas

$35\ in^(2)+5\ in^(2)=40\ in^(2)$
