The following three shapes are based only on squares, semicircles, and quarter circles. find the perimeter and the area of each shaded part. give your answer as a completely simplified exact value in terms of π (no approximations). I need this answer really fast. As soon as possible.

The perimeter of the shaded part is 8πcm and the area of the shaded part is 8πcm and 0.5π(8)² - 8² respectively

Radius, r = 8 cm

= 1/2πr

Perimeter of Shaded part = 1/2 * 2πr

= 1/2 × 2 × π × 8

= 8πcm.

= 1/2πr²

Area of Shaded part

= Area of Quarter-circle - Area of Square

= 0.5π(8)² - 8²

Step-by-step explanation:

Area of Shaded part

= 2 * Area of Quarter-circle - Area of Square

= 0.5π(8)² - 8²

= 32(π - 2)cm².

Perimeter of Shaded part

= 0.5 * 2π(8)

= 8πcm.
