Suppose you are asked to find the area of a rectangle that is 2.1-cm wide by 5.6-cm long. Your calculator answer would be 11.76 cm2 . Now suppose you are asked to enter the answer to two significant figures. (Note that if you do not round your answer to two significant figures, your answer will fall outside of the grading tolerance and be graded as incorrect.)

Enter your answer to two significant figures and include the appropriate units.

Answer #1

Answer – We are given, 2.1 cm wide and 5.6 cm long rectangle and we need to calculate the area of this rectangle.

We know the area of the rectangle = Width * long

                                                  = 2.1 cm * 5.6 cm

                                                  = 11.76 cm2

                                                   = 12 cm2

In two significant figure answer is 12 cm2.

So, the area of a rectangle that is 2.1-cm wide by 5.6-cm long is 12 cm2.
