Mary wants to find the area of the rectangle below.How many unit squares with side length 1/6 yard would mary be able to use to tile the rectangle?

Please Help Me!!! This is really important

Answers

so first find the area
area=legnth times width
area=5/6 times 1/6
5/6 times 1/6=5/36
area=5/36 square units

tile=side legnth 1/6
area of tile=legnth times width or legnth times legnth
1/6 times 1/6=1/36
we must find how many times 1/36 goes into 5/36
divide 5/36 by 1/36
5/36 divided by 1/36=5/36 times 36/1=5/1 times 36/36=5/1 times 1=5

the answer is 5 unit squares needed to tile
