Answer: 37
Step-by-step explanation
Total perimeter = (4x + 1) + (x + 3) + (x + 3) + (4x + 1)
= 10x + 8
10x + 8 = 98
This is because the perimeter of this rectangle is 98 so I have made it equal to the algebraic perimeter.
Now, we can solve the equation to get a value for x.
10x + 8 = 98
10x = 90
x = 9
Now, we substitute x into 4x + 1
4(9) + 1 = 37
