Answer: 2x+10 inches
Explanation:
There are 2 opposite sides that are x inches long, so they add to x+x = 2x
Then there are 2 opposite sides that are 5 inches long, which add to 5+5 = 10
Overall, the four sides add to 2x+10 inches
You could also apply the formula below
P = 2L+2W
P = 2x+2*5
P = 2x+10
That formula is the same as P = 2(L+W)
