Emily is 12, Samantha is 14, and Lauren is 16. Basically all you do to solve this problem is add numbers that are two apart until you find something.
Ex. 2+4+6=12 4+6+8=18 so on and so forth.
First you distribute 4 to 2x and 3. Then after you do that you get 8x+12=10x
[m(100cm/m)(in/2.54cm)(ft/12)]^2=(25/7.62)^2 ft^2
(9*16)m^2(25ft^2/7.62m^2)(sheets/(4*8)ft^2)≈48.44 sheets
In reality you must buy complete sheets, or integer values, so you would need 49 sheets to cover the floor :P
