<PRE><B>Question 14038</B>
Let x = length of the second side, y=length of the first side, and z=length of the third side.
From the question we have,
1.x=length of the second side
2.y=length of the first side = x+3.
3.z=length of the third side = 2x.
4.The sum of these sides, by definition, is the perimeter=59cm
So,
59 = x + (x+3) + (2x).
59 = x+x+3+2x.
59=4x+3.
solve for x.
59-3=4x+3-3
56=4x.
divide by 4 on both sides.
14=x.
Now plug x back into the other formulas.
y = length of the second side = x+3 = 14+3 = 17.
z = length of the thrid side = 2x = 2(14) = 28.
