First, replace each variable in the equation with the value it represents:
You will have 24=2L+2(4)
Now just solve for L
24=2L+8
16=2L
8=L
Your answer is 8.
Be sure to check your answer!

P=2L+2W
24=2L+2(4)
24=2L+8
24-8=2L+8-8
16=2L
8=L A.

If P = 2L + 2W and P = 24, W = 4, then plug in:
24 = 2L + 2*4
24 = 2L + 8
24 - 8 = 2L
16 = 2L
16/2 = L
8 = L ===> the answer's given by option (A)
