No, the number of cows in the barn is 27. You can get this number by subtracting the 83 cows he has from the 56 that are out of the barn.
83 - 56 = 27
If one side of the rectangle is 8 inches, that means the side opposite of it is also 8 inches.
Add those together and subtract it from 30.
8+8=16, 30-16= 14.
You have 14 inches left for the two remaining sides.
Divide 14 by two, which will give you seven.
14÷2=7.
The length is 7 inches.
I hope that helps!
