Question

1. which of the following measurements is the best approximation of 17.85 square feet?

2,385 in²
2,425 in²
2,570 in²
2,690 in²

Explanation:

Step1: Recall square feet to square inches conversion

1 square foot = $12 \times 12 = 144$ square inches

Step2: Calculate total square inches

$17.85 \times 144$
$= (18 - 0.15) \times 144$
$= 18\times144 - 0.15\times144$
$= 2592 - 21.6$
$= 2570.4$

Step3: Match to closest option

2570.4 is closest to 2,570 in²

Answer:

2,570 in²
