Answer:
Region covered by the dominoes is 90 unit²
Step-by-step explanation:
Here we have;
Area half of each domino = 1 unit²
Therefore, area of each domino = 2 unit²
Region where dominoes can be found = 8 × 6 dominoes
Region where dominoes can be found = 48 dominoes area unit²
Number of dominoes omitted = 3 dominoes
Therefore, total number of dominoes in region = 48 - 3 = 45 dominoes
Region covered by the dominoes = 45 × 2 unit² = 90 unit².
