Answer:
first option
Step-by-step explanation:
The perimeter is the distance around the composite shape, which is composed of a rectangle and a semi- circle.
P = 12 + 16 + 12 + πr ← ( rectangle and semi- circle )
= 40 + (3.14 × 8)
= 40 + 25.12
= 65.12 in
----------------------------------
A = (16 × 12) + (0.5πr² ) ← rectangle and semi- circle
= 192 + 0.5 × 3.14 × 64)
= 192 + 100.48
= 292.48 in²
