The commutative property of multiplication.
48 6x8=48
If two of the sides are 6 and 8, the sum of all four sides is 6 + 8 + 6 + 8, which is 28. Then as soon as you find out what the units are, you'll be all ready to go to Lowe's. :)
6, 8, and 10. To figure this one out, it is trial and error, so pick random numbers. 4x6=24 8x8=64, difference of 40, not big enough. 6x8=48 10x10=100 difference of 52. So, the right answer is 6, 8, and 10.
Lots of combinations equal 50, here are a few.... 1+49, 2+48, 3+47, 4+46 and so on 2x25, 5x10, 10x5 etc. 300/6, 1200/24, 12+8=20+30 or.. 3x10=30+20, 3x14=42+8, 6x8=48+2 ..... we could be here a long time, you get the idea!
