Question

Part A: Half of each domino is one square unit. Find the area, in square units, of

the region covered by the dominoes without counting every square.

Answer 1

Region covered by the dominoes is 90 unit²

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.
