Question

The figure below shows three circles, each of
radius 25 and centres at P, Q and R respectively.
Further AB = 6,CD = 12 and EF
12 and EF = 15. What is
the perimeter of the triangle PQR

Answer 1

Answer:

perimeter of ∆ PQR is 165

Answer 2

Answer:

each radius =25, then PB=PA+AB

=>25=PA+6, PA=19=BR

Step-by-step explanation:

likewise QC=QD+DC =>25=QD+12, QD=13=RC

PE=PF+FE=>25=PF+15, PF=10=EQ

Perimeter=PA+AB+BR+RC+CD+DQ+EQ+EF+FP

=>19+19+6+13+13+12+10+10+15
