Answer:
The length of the other leg is [tex]3.21\ units[/tex]
Step-by-step explanation:
I will assume that the triangle is a right triangle
In a right triangle the legs are perpendicular
so
The area of a right triangle is equal to
[tex]A=\frac{1}{2}(a)(b)[/tex]
where
a and b are the legs of the triangle
In this problem we have
[tex]a=39.2\ units[/tex]
[tex]A=63\ units^{2}[/tex]
substitute the values
[tex]63=\frac{1}{2}(39.2)(b)[/tex]
[tex]126=(39.2)(b)[/tex]
[tex]b=126/(39.2)=3.21\ units[/tex]
