Question

jhonyy9 · Answer

how you get area of a rectangle ?

Evo · Answer

you do a times b

WhipStreak23 · Answer

So what is a and b here?

old question but will respond so this can be closed

this question confused me at first because there should only be one possible area for this set of measurements, but apparently they want you to consider the margin of error

this is hard to explain, but to find margin of error, take the measurement, go to the smallest unit of that significance, then divide by 2 to find the margin of error (sorry if this is confusing, I'll demonstrate)

since you have 6, we consider "1" as the smallest unit, then divide by 2 to get a margin of error of +/- 0.5

so with the margin of error, the unit of measurement is (6 +/- 0.5) meaning that the smallest possible measurement that rounds to 6 is 5.5 (@ 1 significant digit), and the largest is 6.5 (technically 6.4999999 cont. but whatever).

same logic with 11 (11 +/- 0.5)

calculate the smallest possible area and the largest possible area, using the smallest possible dimensions and the largest possible dimensions
