Question

The length of a rectangle l=10.5cm breadth b=2.1cm and the mimimum possible measurement by scale =0.1cm then area is....

Answer 1

Your answer is 22 sq. Cm
The accurate answer is 22.05 but as the min possible measurement is 0.1cm the answer would be 22sq.cm

Answer 2

Answer:

22.0cm^2

Explanation:

area = length × breadth

a= 10.5 × 2.1

a = 22.05 cm^2

so if we do round ( scale of it) of it then we get,

area = 22 .0 cm^2

make sure that 22 and 22.0 are different values because if we see from options point of view because if the examiner gives you both 22 and 22.0 answers in options then what you will do so correct ans from my point of view is 22.0 cm^2.
