Hello!
7.5 * 4 is equal to 30
7 * 4 = 28
.5 * 4 = 2
28 + 2 = 30
I hope this helps, and have a nice day!
Your question is incomplete.
L=25
If the length is 25 yards then you use 50 yards of fencing for the length, this leaves ten yards for each width of fencing each.
10 yards is 15 yards less than 25 yards showing that this is the correct answer.
