The perimeter of the shaded part is: 25.1 cm.

The area of the shaded part is: 36.6 cm².

How to Find the Perimeter and Area of the Shaded Part?

Area = Area of square - 2(area of square - area of quarter circle) = s² - 2(s² - 1/4πr²).

Parameters given are:

  • s = 8 cm
  • r = 8 cm

Plug in the values into the equation

Area = 8² - 2(8² - 1/4π(8²)).

Area = 64 - 2(64 - 50.3)

Area = 36.6 cm²

Perimeter = 2(perimeter of quarter circle) = 2(1/4(2πr)) = 2(1/4(2π8)) = 25.1 cm
