17ft

Explanation:

I expect the question is to find perimeter of triangle PQR .
There are two triangles given (PQR , STU) These are congruent by SAS
PQ=ST
QR=UT
angle PQR= angle STU
triangle PQR ~= triangle STU (SAS congruence rule)
using the property CPCT (corresponding parts of congruent triangles)
3y-2=y+4
3y-y=+4+2
2y=6
y=3;
perimeter of triangle PQR =6+4+3(3)-2
10+9-2 = 17 ft
