Answer:
So the perimeter of the rectangle is 33y + 1 feet.
Explanation:
Let's call the width of the rectangle "w" and the length "l". From the given information, we have:
w = 7y - 9.5
l = 9.5y + 10
The perimeter of a rectangle is equal to the sum of the lengths of all four sides, so we can find the perimeter by adding up the values of w and l:
P = 2w + 2l
= 2(7y - 9.5) + 2(9.5y + 10)
= 14y - 19 + 19y + 20
= 33y + 1
So the perimeter of the rectangle is 33y + 1 feet.
