You can put this solution on YOUR website! The length of a rectangle is six times it's width if the area of the rectangle is 294 in to the 2 power find it's perimeter.
***
let x=width
6x=length
length*width=area
x(6x)=294^2
6x^2=294^2
x^2=294^2/6
x=294/√6
x≈120
6x≈720
perimeter=2(length+width)=2*840=1680 inches
