Find the midpoint of AC.B(0, a)C(a, a)A(0,0) D (a,0)Enter the value thatabelongs in the green box.Midpoint Formula: M = (*3*X2Yzzy)Yi+y2([?]:2Enter

Using the formula given,
[tex]\begin{gathered} x=\frac{0+a}{2} \\ \\ \rightarrow x=\frac{a}{2} \end{gathered}[/tex][tex]\begin{gathered} y=\frac{0+a}{2} \\ \\ \rightarrow y=\frac{a}{2} \end{gathered}[/tex]Thereby, the midpoint is:
