The rule is that When multiplying values, determine which value has the least number of significant figures. That is how many significant figures the result must have.
Here area of plot = area of rectangle
= length × breadth
= 15.4 cm × 11.7 cm
= 180.18 cm²
but according to rule of significant figure of multiplication as above mentioned.
least significant figure is 3
so, area of plot = 180. cm²
option should be 180 cm² because it is most accurate representation rather than 180.2 cm² or 180.18 cm².
but yes, 180.2 cm² more accurate than 180.18cm²
