#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#
