Answer:

  • y = 2.5 ft
  • 4y = 10 ft

Step-by-step explanation:

The perimeter is the sum of the side length. Each of the sides shown has the same length as its opposite, so the perimeter is ...

  P = 2(4y +y) = 10y

Using the given value for perimeter, we find y to be ...

  25 ft = 10y

  2.5 ft = y

__

Then the longer side is ...

  4y = 4(2.5 ft) = 10 ft . . . . length of longer side
