The answer is 27 tiles !

21 white tiles × 3  = the total area it takes up!

21 × 3 = 63

144 - 63 = 81

81 is the area left!

Divide by 3 to find how many black tiles are needed!

81÷ 3 = 27

Hope I Helped !

Answer:

48

Step-by-step explanation:

21 white tiles = 63 cm2

total number is 144

144-63 = 81

81/3 = 27

so 27 black tiles

21+27 = 48 total.
