Answer:
10 inches
Step-by-step explanation:
To find the length of the desk, you need to use the perimeter equation and isolate for the length. Substitute the variables with what you know,
[tex]P = 2(L+W)\\48 = 2(L + 14)\\\frac{48}{2} = L + 14\\ 24 = L +14\\24 - 14 = L\\10 = L[/tex]
Therefore, the length of the desk is 10 inches.
