PLEASE HELP!!

x=7.5

Total area = 27+15 = 42

Step-by-step explanation:

For question 13, we still need to find the bottom side of the T-shape that's not labeled. That's just 9-3.5-3.5=9-7=2.

Now that we know all the side lengths, we can set up an equation where all the side lengths add up to 39, and solve for x:

9+3+3+3.5+3.5+x+x+2=39

24+2x=39

2x=15

x=7.5

For question 14, we can divide the shape into 2 rectangles, which is shown in the picture attaches. Then, we just solve for each rectangle's area separately, and then add them up.

Rectangle A = 9*3=27

Rectangle B = 7.5*2=15

Total area = 27+15 = 42
