The dimensions are 7 by 12 meters Check: perimeter = 2*(7+12) = 38 meters and area = 7*12 = 84 square meters
38-50 = -12
volume of soil needed = 38*5*1=190sq ft .12" = 1 feet
38 + 12 = 50:D

There is no need to estimate: 38 - 12 = 38 - (10 + 2) = 38 - 10 - 2 = 28 - 2 = 26.
38/s - 7 = 12 multiply through by s 38 - 7s = 12s 38 = 19s 2 = s check 38/2 - 7 = 12 19 - 7 = 12 12 = 12 checks
38 - 19 + 12 = 31
50-38 = 12

12/38 in simplest form is 6/19. Meaning 12/38 is both divisible by 2.
