PS = 12 cm (6+6)
As PQ = QR = RS

➧ PQ = QR = RS
➾ 1/3 × PS
➾ 1/3 × 12
➾ 4 cm

QS = 2 PQ
QS = 2 × 4
   = 8 cm

➧ Area of shaded region =
Area of semicircle with PS as diameter + Area of semicircle with PQ as diameter - Area of semicircle with QS as diameter.

➾ ½ [3.14 × 6² + 3.14 × 2² - 3.14 × 4²]

➾ ½ [3.14 × 36 + 3.14 × 4 - 3.14 × 16]

➾ ½ [3.14 (36 + 4 - 16)]

➾ ½ (3.14 × 24) = ½ × 75.36

➧ Area of shaded region,
➾ 37.68 cm²

➧ Perimeter 0f shaded region,
➾ 12 × 22 / 7
➾ 264 / 7
➾ 37.68 cm²...✔
