Question 864900
x and y dimensions.
A = 5985
p = 316


2x+2y=p, xy=A,
{{{y=(p-2x)/2}}}
Substitute into A equation.
{{{(x)y=A}}}
{{{(x)(p-2x)/2=A}}}
{{{px-2x^2=2A}}}
{{{-2x^2+px-2A=0}}}
{{{2x^2-px+A=0}}}
{{{highlight(x=(p+- sqrt(p^2-4*2(A)))/(2*2))}}}   Use the one which makes sense, usually with the postive or add square root.
-
Return to perimeter OR area equation and calculate for y.
{{{highlight(y=(p-2x)/2)}}}.
-
Compute x and y using the given values in the problem description.
