321 in.
327 in.

Answer 18

oh i see, so this is a rectangle 321 inches by 327 inches?

Answer 19

yeah

Answer 20

how big is one tile?

Answer 21

12 inches

Answer 22

so 12 inches by 12 inches?

Answer 23

yup

Answer 24

ok thanks

Answer 25

The total area is 321 x 327 = 104,967 square inches

Each tile is 12 x 12 = 144 square inches

So divide the total area by the area of one tile to get

104,967/144 = 728.9375

Then round up to get 729

So she needs 729 tiles

Note: she will cut the last tile to get the 0.9375 square inches.
