Question 934761
L = 2w
Lw = 5000
---
Lw = 5000
(2w)w = 5000
2ww - 5000 = 0
ww - 2500 = 0
---
the above quadratic equation is in standard form, with a=1, b=0 and c=-2500
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 0 -2500
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic has two real roots at:
---
w = 50
w = -50
---
the negative root doesn't fit the problem statement, so use the positive root:
---
w = 50
L = 2w
L = 100
---
answer:
w = 50 ft
L = 100 ft
