<PRE><B>Question 930169</B>
b = h + 9
a = bh/2 = 266
---
bh/2 = 266
bh = 266*2
(h + 9)h = 266*2
hh + 9h = 532
hh + 9h - 532 = 0
---
the above quadratic equation is in standard form, with a=1, b=9 and c=-532
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 9 -532
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic has two real roots at:
---
h = 19
h = -28
---
the negative root doesn&#39;t fit the problem statement, so use the positive root:
---
h = 19
b = h + 9
b = 28
---
answer:
h = 19 inches
b = 28 inches
