Two sides are 3x longer than the shortest side. So, set up your problem like this.
X = unknown length in centimeters
3X = length of two longer sides
1X = length of short side
3x + 3x + 1x = 49
7x = 49
x = 7
So, two longer sides are 21 centimeters each and the short side is 7 centimeters.
21+21+7 = 49
Is this asking about surface area or volume?
