Question

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

Answer 1

Answer:

D.60

Step-by-step explanation:

Area= L*W (we are changing the area)

5*8=40 (the area of the old)

10*10= 100 (area of new)

100-40 = 60 (number of tiles to get to new from old)

Hope this helps

Answer 2

Answer:

D) 60

Step-by-step explanation:

Rose's patio originally had 5 x 8 = 40 tiles (drawn in blue)

since she wants to put more tiles and form a 10 x 10 square, she will need to add: (10 x 10) - 40 = 100 - 40 = 60 tiles (white tiles)
