Answer:
27 tiles
Step-by-step explanation:
Here is the complete question :
Todd uses 21 white tiles and some black tiles to make a mosaic.the mosaic has a total area of 144 square centimeters. Each tile has an area of 3 square centimeters. How many black tiles did Todd use
<u><em>Steps to take to determine the answer</em></u>
- Determine the total area of the white tiles used. This can be determined by multiplying the number of white tiles by the area of a tile
- subtract the area of the white tiles from the total area of the mosaic.
- Divide the answer derived in the previous step by 3
Area of the white tile = area of each tile x total white tiles used
3 x 21 = 63cm²
144cm² - 63cm² = 81cm²
Number of black tiles used = 81cm² / 3cm² = 27 tiles
