Answer:
The length of the sides are 9 units, 18 units and 11 units
Step-by-step explanation:
Let
x ----> one side of the triangle
y ----> the longest side of the triangle
z ----> the third side of the triangle
we know that
The perimeter of triangle is equal to

we have

so
----> equation A
-----> equation B
----> equation C
substitute equation B and equation C in equation A
solve for y


<em>Find the value of x</em>
---> 
<em>Find the value of z</em>
----> 
therefore
The length of the sides are 9 units, 18 units and 11 units
