2A. Answer is 42.7. C squared minus B squared equals A squared. C^2 - B^2 = A^2. 48^2 - 22^2 = 42.66^2.

Answer:

P = 157.1 mm

Step-by-step explanation:

The perimeter of the figure = Circumference of circle + perimeter of square

We have, d = 11

⇒ Radius = 11 mm

Side of square = 22 cm

So,

$P=2\pi \times 11+4\times 22\\\\P=157.11\ mm\\\\or\\\\P=157.1\ mm$

So, the perimeter of the figure is equal to 157.1 mm.
