The width is #4.648# feet and the length is #23.238# feet

Explanation:

We know the length in terms of the width.

Let the width of the table be #x# feet.
Therefore the length is #5x# feet.

#A = l xx w#

The area of the table is given so you can write an equation:

#5x xx x = 108#

#5x^2 = 108" "larr div 5#

#x^2 = 21.6#

#x = sqrt21.6" "larr# only the positive root needs to be used,

#x = 4.648# feet is the width

#5x = 23.238# feet is the length
