Question

Rhys will tile the rectangle below to find it’s area(3/10 foot, 4/5 foot). How many unit squares with side lengths 1/10 foot will Rhys use to tile the rectangle?

Answer 1

Okay, here we have this:

Considering the provided rectangle, we are going to calculate how many unit squares does he need, so we obtain the following:

First we will calculate the area of the given rectangle and then we will divide the area by the area of each tile that will be used, so we have:

Area of the rectangle=(3/10)*(4/5)=12/50=6/25ft^2

Tile area=(1/10)*(1/10)=1/100ft^2

Finally we will calculate the number of tiles by dividing the total area by the area of the tiles:

Number of tiles=(6/25ft^2)/(1/100ft^2)

Number of tiles=600/25

Number of tiles=24

Finally we obtain that the correct answer is the option A.
