The area of a rectangular field (in m2) of length 55.3 m and breadth 25 m after rounding off the value for correct significant digits is
- A138 101
- B1382
- C1382.5
- D14 102
View written solutionFree
Correct answer: D
Area = Length $\times$ Breadth
= 55.3 $\times$ 25 m2
= 1382.5 m2
= 14 $\times$ 102 m2 (Rounding off of two significant figures)
