Rose has a rectangular patio that is 5 tiles long and 8 tiles wide. She is changing the dimensions to 10 tiles long by 10 tiles wide. Draw a picture to determine how many new tiles Rose will add to her patio. A. 5
B. 50
C. 60
D. 100

C. 60

Step-by-step explanation:

First we mjust know that area is length times width (this will be the key to help you)

To find the old area we must: 5*8=40

Then we must find the new area: 10*10 = 100

Now we must subtract the tiles to get the new from old: 100-40=60

Therefore, your answer is 60.
