You didn’t tell us how you want to figure it out
1st strategy: Add the first two terms and the last two.
16+35 + 24+14
51 + 38 = 89
2nd strategy: add the first and last term and the middle 2 terms.
16 + 35 + 24 + 14
30 + 59 = 89
The area of the rectangle would be 45 m^3
1/2 I guess I don't think you typed in the question correctly. Not trying to be mean.
Say you had the numbers 3 and 4. The LCM is the lowest number that both 3 and 4 will factor into.
The multiples of 4: 4,8,12,16,20,24
The multiples of 3: 3,6,9,12,15,18,21,24
They both factor into 12 and 24 but 12 is the least common multiple or smallest number they both go into :) I really hope this helps!! :)
