The longest side of a triangle is six more units than the shortest side. the third side is twice the length of the shortest side. of the perimeter of the triangle is 25 units, write and solve an equation to find the lengths of all three sides of the triangle.

Short side = s

 

Longest side    = s+6

 

third side =  2 *s = 2s

 

added together they equal 25

 

s   +  s+6   +   2s  = 25

4s +6 = 25

4s = 19

s = 19/4

Longest  ==   43/4

third side = 19/2
