Question 26213
easy :-)


Let second side be x
then first is x-5
and third is 2(x-5)


perimeter is (x-5) + x + 2(x-5) = 33
--> x - 5 + x + 2x - 10 = 33
4x - 15 = 33
4x = 48
x = 48/4
x = 12cm


So, first side is 7cm
second is 12cm
third is 14cm


-->check: these 3 add to give? 33cm, the perimeter, so correct!
