Question

1. nb lbe = 0,624 x 16 = 9,984/16 -> 10/16 réponse : 243,9 10/16
2. calculer la surface dun plancher qui fait 10^-5 de long par 12^-3 de larg (réponse en m²) :

s = long x larg
s = 10^-5 x 12^-3

Explanation:

Step1: Convert length to meters

First, convert 10'-5" to decimal feet: $10 + \frac{5}{12} \approx 10.4167$ ft. Then convert to meters: $10.4167 \times 0.3048 \approx 3.174$ m.

Step2: Convert width to meters

Convert 12'-3" to decimal feet: $12 + \frac{3}{12} = 12.25$ ft. Then convert to meters: $12.25 \times 0.3048 \approx 3.734$ m.

Step3: Calculate area

Multiply length and width: $3.174 \times 3.734$

Answer:

$\approx 11.85$ m²
