Traditional:
30x10.6=300+18=318
Alternate:
must be a whole number b/c .6x a mutiple of ten cannot end in a decial (eliminates 81.2)
aproximat the last part 30x10 ~ a little bigger than 300. Your remaining choices "318.0 and 318" are the same (unless you are looking at scientific notation, its been a while since then)

Come on now. How do you find an area? Imagine a square 10 feet by 10 feet...how many little squares would that make? 100!
That's 10 x 10 = 100
So how do you get the area of a rectangle? Same way!

r u trying to ask how many significant figures must there be in the answer? well the number of significant figures after multiplication or division is equal to the number of significant figures of the least accurately known quantity. in this case the answer is 318 in squared

Area = length x width so multiply the length (30.0) by the width (10.6).

Rectangle l and w are the lengths of the rectangles sides (length and width). 30.0inx10.6in=318in^2
