Question

The perimeter of a desk is 48 inches a the width of the desk is 14 inches. What is the length of the desk? And remember to use an equation, label and circle your answer. P= L+L+W+W or P= 2L+2W or P= 2(L+W)​

Answer 1

10 inches

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,

`P = 2(L+W)\\48 = 2(L + 14)\\(48)/(2) = L + 14\\ 24 = L +14\\24 - 14 = L\\10 = L`

Therefore, the length of the desk is 10 inches.
