Answer:
120.9
Explanation:
First, there are two pictures with length 22.65" (" means inches)
So, multiply 22.65 * 2 = 45.3
Then add banner length:
54.3 + 45.3 = 99.6
Now, you need to add the spaces between. There are two spaces from the banner to each picture, so take that lengths of 6.45 and multiply by 2.
6.45* 2 = 12.9
Then, do the same with the length for the pictures to the end of the board.
There are two photos, both 4.2" away, so multiply it by 2.
4.2*2= 8.4
Now, add all of the bolded numbers together to get the total length.
99.6 + 12.9 + 8.4 = 120.9
