We have expression:

4 (2x) + 4 (x)

Number 4 represents number of legs for each table.

x represents length of shorter legs, for a coffee table

2x reoresents length of longer legs, for a kitchen table

4 (x) represents 4 times the length of one leg for coffee table. This is the amount of material needed for all 4 legs of coffee table.
