Answer:

first option

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
