Answer:

1. P = 13.254

2. P = 6.64 + 2x

6. P = 10

Explanation:


1.\\\text{The length of semicircle:}\\\\l=(1)/(2)d\pi\\\\d-diameter\\\\d=2.2\\\\\text{substitute:}\\\\l=(1)/(2)(2.2)\pi=1.1\pi\approx(1.1)(3.14)=3.454\\\\\text{The perimeter of the figure:}\\\\P=2(3.8)+2.2+3.454=13.254


2.\\P=2(3.32)+2x=6.64+2x


6.\\\text{Look at the picture.}\\\\P=4(2)+2(1)=8+2=10
