Th vertices of a sandbox are p(12, 14), q(12, 17), r (16, 17) and s (16, 14).the coordinates are measured in feet . what is the perimeter of the sandbox ?

So we just find the distance between the points found by using the formula
d= where points you have the points (x₁,y₁) and (x₂,y₂) so subsitute

using the formula we get that the sides are legnths (note: pQ means the line that is drawn from point p to point Q)

pQ=3 ft
QR=4 ft
RS=3 ft
Sp=4 ft

add
3+4+3+4=14 ft

perimiter=14 ft

Hope i can you!
