49 feet
Explanation:
We know that the longer side = 16 because the other long side = 16 and they are parallel
Now, you do:
4x + 3 = 16
subtract 3 from both sides
4x = 13
divide by 4
13/4 = 3.25
X = 3.25
Now, to find the shorter sides, just substitute x
2x + 2
2(3.25)+2
6.5 + 2 = 8.5
We know that the other short side is congruent to 2x + 2 because they are parallel lines
Now that we have all our sides, add them up
16 + 16 + 8.5 + 8.5
You get your answer of: 49 feet
