Answer:

I'll setup the problem, then you can do the calculations

Step-by-step explanation:

Perimeter = 2width(W) + 2length (L)

Area = LW

L = 2.5 + 2W

LW = 62.5

substitute L in equation for area

2.5W +  {2W}^{2}  = 62.5 \\  \\  {2W}^{2}  + 2.5 - 62.5 \\  \\  use \:  quadratic \:  solution \\\frac{ - b ±  \sqrt{ {b}^{2}  - 4ac}}{2a}

a = 2; b = 2.5; c = 62.5
