An area cannot be 30m since that is a linear measure, not the measure of an area. The lowest perimeter, for an area is attained by a circle. So for an area of 30 m2 this was attained by a circle of radius R, then πR2 = 30 so that R2 = 30/π and R = sqrt(30/π) The perimeter = 2*π*R = 2*π*sqrt(30/π) = 2*sqrt(30*π) = 19.42 metres

120m^3/30m^2 = 4 meters

Let ABCD be the border of square garden of side 30m and the shaded region be the path Then AD = 30m , XP=1m, SY = 1m and XY = AD ⇒ XP + PS + SY = AD ⇒ PS = AD - XP - SY = 30m - 1m - 1m = 28m ∴ PQRS in a square of side 28m ∴ The area of path = Area of ABCD - Area of PQRS

The dimensions of the rectangular lot are: 30m by 15m
The GCF of 12m, 15m and 30m is 3m.
30m (meters) is 98.425 feet or 16.4 fathoms.
