Pls help
Please write down the step by step of how to do it.. thanks a lot

a. 29

b. 9.1

Step-by-step explanation:

General = The perimeter is all the sides added togther.

a. x is given to you, so you just add all the numbers.

b. Now the perimeter is given, but not x. So add the numbers you can see. That would be 9+6.5+4.7= 20.2

So something + 20.2 has to equal 29.3

29.3 - 20.2 = 9.1.

I did not answer c. because I'm not very confident that my answer would be right. With my explainaion I hope you can figure it out easily enough. Good Luck!
