Given:
11.7 cm by 15.4 cm
To get the area of a plot, we multiply its length and its width.
Since two measurements are given, it is safe to assume that the higher measurement represents the length of the plot and the lower measurement is its width.
Length = 15.4 cm
Width = 11.7 cm
Area = Length * Width
Area = 15.4 cm * 11.7 cm
Area = 180.18 cm²
