Question 348669
Hi,
Note: the perimeter is the sum of the lengths of the sides of the triangle.
Let l represent  the longest side
.
Write as You Read (let l be the longest side
shortest side is (l-4)
"other side" is half the sum of l and (l-4)
.
{{{l + (l-4) + (l+(l-4))/2 = 24}}}
.
simplfy
{{{2*l - 4 + (2*l-4)/2 = 24}}}
.
{{{2*l - 4 + (l-2) = 24}}}
{{{3*l - 6 = 24}}}
{{{3*l = 30}}}
l=10ft
shortest side is 6ft
Other side is 8ft
.
check Your answer
10ft + 6ft +8ft = 24ft
