Question 897327
Find the perimeter in terms of the sides : SS - short side, MS - middle side, LS - long side.
{{{SS+MS+LS=3075}}}
Now get all sides in terms of the middle side.
{{{SS=MS-75}}}
.
.
{{{LS=MS+375}}}
Substitute into the perimeter.
{{{(MS-75)+MS+(MS+375)=3075}}}
{{{3MS+300=3075}}}
{{{3MS=2775}}}
{{{MS=925}}}
Now go back and plug in this value to find SS and LS.
