Question 386732
Let x= width
2x= length


Area = W*L
Area = x*2x=50 Square Inches


2x^2=50


Divide both sides by 2:
x^2=25


There are two solutions:  x=5 and x=-5.  However, you have to reject any negative values, since you can't have a negative width.


x=5 inches = WIDTH
2x=2*5 =  10 inches = LENGTH


Check:  Area = W*L=5*10= 50 square inches.


Merry Christmas!!
