Method 1)
2,400 person (3 ft² / person) = __?__ m² .
The units of "person" ; 'cancel out"; since "person/ person" = 1 ; and 1/1 = 1.
and we have: "2,400 * (3 ft²) = 7, 200 ft² .
______________________________________
We are ask to find the value, in units of "m² " ;
______________________________________
→ So; we convert "7, 200 ft² " ; to "m² " ;
______________________________________
→ Note the conversion: 1 m² = 10.7639 ft² ;
______________________________________
→ 7, 200 ft² * [ ( 1m²) / ( 10.7639 ft²) ] ;
= [ (7, 200 ) / (10.7639 )] m² ;
= 668.9025353264151469 m² ;
⇒ Round to 668.903 m² .

Method 2)
______________________________________
2,400 person (3 ft² / person) = __?__ m² .
Since we want the answer is units of: "m² " ;
___________________________________________
Let us convert: "3 ft² " to units of: "m² " ; and then rewrite the problem.
___________________________________________
→ Note the conversion: 1 m² = 10.7639 ft² ;
___________________________________________
= [ (7, 200 ) / (10.7639 )] m²
= 668.9025353264151469 m²
⇒ Round to 668.903 m² .

Method 3)
______________________________________
2,400 person (3 ft² / person) = __?__ m² .
______________________________________
→ Note the conversion: 1 m² = 10.7639 ft² ;
______________________________________
(2,400 person) * (3 ft² / person) * [ ( 1m²) / ( 10.7639 ft²) ] ;
= { [ (2,400) * (3) * (1) ] / [ 10.7639 ] } m² ;
= { [ (2,400) * (3) ] / [ 10.7639 ] } m² ; {Note: The "1" can be ignored.}.
= [ (7,200) / (10.7639) ] m² ;
= 668.9025353264151469 m² ;
⇒ Round to 668.903 m² .
