Question

On an official united states flag, the ratio of width to length is exactly 1 to 1.9. What is the area of a United States flag whose width is 2 feet.

Answer 1

$\frac{1}{1.9}=\frac{2}{x}\\\frac{1.9}{1}=\frac{x}{2}\\\frac{1.9(2)}{1}=\frac{x(2)}{2}\\\frac{3.8}{1}=x\\x=3.8\\\\A=lw\\A=(3.8)(2)\\A=7.6$

The area is 7.6 feet.
