P=32

Explanation:

.

A(0,0),B (6,8),C (12,0)

We use the distance formula to find the length of each side. Then we add them together. The distance formula is:

d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)

AB=sqrt((6-0)^2+(8-0)^2)=sqrt(36+64)=sqrt100=10

BC=sqrt((12-6)^2+(0-8)^2)=sqrt(36+64)=sqrt100=10

AC=sqrt((12-0)^2+(0-0)^2)=sqrt(144+0)=sqrt144=12

P=AB+BC+AC=10+10+12=32
