Question

Brian is creating a collage on a piece of cardboard that has an area of 160r4 square centimeters. The collage is covered entirely by pieces of paper that do not overlap. Each piece has an area of the square root of r to the seventh power square centimeters. Use the given information to determine an expression for the total number of pieces of paper used

Answer 1

Well, since you know the area of the whole thing, and you know the area of each individual piece, what would you do to find the total number of pieces?

Answer 2

Think of this: if I have a piece that is 10 sq. in in total area, and I have pieces that are 1 sq in each, how would you determine the total number of pieces?
