Answer:
HERE YOU GOOO!!!!!
Step-by-step explanation:
1. locate the incenter by constructing the angle bisectors of at least two angles of the triangle.
2. construct a perpendicular from the incenter to one side of the triangle to locate the exact radius.
3. place compass point at the incenter and measure from the center to the point where the perpendicular crosses the side of the triangle (the radius of the circle).
4. draw the circle.
 
        
             
        
        
        
Answer:
1587.6 m²
Step-by-step explanation:
 where b is the base length and h is the height (b and h on the triangle will always be perpendicular to each other)
 where b is the base length and h is the height (b and h on the triangle will always be perpendicular to each other)
Plug in 75.6 m as b and 42 m as h

I hope this helps!
