Question

HELP PLEASE!!A(5,1), B(7,1), C(7,6), D(5,6) What is the perimeter of rectangle ABCD?

Answer 1

`\begin{gathered} \text{The distance betw}ee\text{n the AB is } \\ d_1=\sqrt[]{(1-1)^2+(7-5)^2} \\ d_1=2 \\ \text{Now, the distance betw}en\text{ the C and D,} \\ d_2=\sqrt[]{(6-6)^2+(5-7)^2} \\ d_2=2 \\ \text{The perimeter o the rectangle is,} \\ P=2(d_1+d_2) \\ P=2(2+2) \\ P=8\text{ unit} \end{gathered}`
