Also I think the answer is 55
this triangle has 3 sides one is 12, lets call this side a²
another side is 72, lets call this side c²
this triangle must follow Pythagoras therom if it is right angled, that is a²+b²=c²
where a and b are the two shorter sides and c is the longest side (called the hypotenuse) opposite the right angle
to find the last side you do 72² - 12² = 5040
but it is the square root of 5040 which is 70.99 (two decimal places) if you want it in decimal form, if you want it in surd form it is √5040
So triangle has 3 sides
represent them as x,y,z
so lets say x=shortest side
y=2nd side
z=longest side
x is 1/2 of the second side
x=1/2(y)
shortest side is 1/3 of the longset side
x=1/3(z)
how does the triangle compart the longest side (z)
x+y+z=perimiter
solve to subsitute and convert all values to z
x=1/2y
2x=y
2(1/3z)=y
2/3(z)=y
and x=1/3(z)
therefor, subsitute so that there are only z terms
1/3(z)+2/3(z)+z=perimiter
add like terms
3/3(z)+z=p
z+z=p
2z=p
the peimiter is 2 times of the longest side
