Question 980327
L=length; W=width; A=Area=450m^2; P=Perimeter=86m
.
{{{P=2(L+W)}}}
{{{86m=2(L+W)}}}
{{{43m=L+W}}}
{{{43m-W=L}}}
.
{{{A=LW}}}
{{{450m^2=LW}}}
{{{(450m^2)/W=L}}}
.
{{{450/W=43-W}}}
{{{450=43W-W^2}}}
{{{W^2-43W+450=0}}} 
{{{(W-25)(W-18)=0}}}
{{{W-25=0}}} {{{OR}}} {{{W-18=0}}}
{{{W=25}}} {{{OR}}} {{{W=18}}}
.
ANSWER: The width is 25 meters or 18 meters, and the length is the other
(For width=25 meters, length=18 meters and for width=18 meters, length=25 meters)
