From the question, we were asked that how many 42 inches wide panels must be bolted together to create a 28 feet wall.
First let's covert the two measurement to same unit.
So, lets convert 42 inches into feet.
Recall, 1 foot will give 12 inches
42 inches will be:
42/12 = 3.5 feet
Therefore, the wide wall that must be bolted together to create a 28 feet wall is:
= 28/3.5
= 8 feet.
