PQR is the diagram of a semicircle RSP with centre at Q and radius of length 3.5cm. If QPT = 60^o. Find the perimeter of the figure PTRS. $\pi$ = $\frac{22}{7}$

25cm

18cm

36cm

29cm

25.5cm

Correct answer is A

Circumference of PRS = $\frac{\pi}{2}$ = $\frac{22}{7}$ x $\frac{7}{1}$ x $\frac{1}{2}$

= 11cm

Side PT = 7cm, Side TR = 7cm

Perimeter(PTRS) = 11cm + 7cm + 7cm

= 25cm
