Answer:
The length of the rectangle is 6 ft while the width is 3 ft.
Explanation:
The formula for finding the area of a rectangle is
area = width x length and vice versa
lets substitute the numbers that we already know
18 = w x 2w
We know from our times tables that 2 times 9 equals 18, and also that 3 times 6 equals 18.
6 is two times 3, so that works out!! Lets give it a try
18 = 3 x 3(2)
18 = 3 x 6
18 = 18 !!!
and we are done!
