Answer:
x = 0.625
Explanation:
On the shorter sides, they increase by two (goes from two to four)
So, you can assume that the longer side on the bigger rectangle is equal to 12
16x + 2 = 12
subtract 2 on both sides
16x = 10
Divide by 16 on both sides
x = 0.625
You can check by
16(0.625) + 2 = 12
I hope this helps!!
