Question 1205954
<pre>
In a triangle, the shortest side is 3 meters less than the longest side. 

(a) {{{S=L-3}}}

The length of the third (medium) side is 11 meters less than twice the length 
of the longest side.

(b) {{{M=2L-11}}}

 If the perimeter is 22 meters, 

(c) {{{S+M+L=22}}}

Substitute (a) and (b) in (c)

{{{(L-3)+(2L-11)+L=22}}}

{{{L-3+2L-11+L=22}}}

{{{4L-14=22}}}

{{{4L=36}}}

{{{L=9}}}

Substitute in (a)

{{{S=9-3}}}

{{{S=6}}}

Substitute in (b)

{{{M=2L-11}}}

{{{M=2(9)-11}}}

{{{M=18-11}}}

{{{M=7}}}
