Step by Step Solution
Step 1
The picture below shows the square with sides of length L.
Step 2
Since the value of the area is given as 16in2, we can substitute A with 16 as shown below:
Step 3
Now, we have L2 = 16. Since L square is a multiplication of L twice, we can find L by taking the square root of 16. This is shown below:
Step 4
Now, the calculated number 4, has no meaning until we include the unit for it. Since the area is in in2, L will be in inch. Hence:
L = 4 in
Step 5
Therefore, the answer is B.
