Answer:26
Step-by-step explanation: As the shape is a rectangle we know that the opposite sides are equal.
So Side DC = Side AB = 5y + 1 and Side DA = Side CB = 4y+2.
Using the information above, we can then write out the equation:
2(5y + 1 + 4y + 2) = 96
After simplifying it, we would get:
2(9y + 3)=96
9y + 3 = 48
9y = 45
y = 5
We can then plug in the value of y into the equation 5y+1:
5y + 1
5(5) + 1
25 +1
