An equation is used to represent expressions with equal values. The equation to find the value of b is:![55.5ft = 5b + 10.5ft](/tpl/images/2467/6342/9b7f3.png)
Given that:
To get the value of distance b, we simply add up the length of every item that makes up the cross-section.
So, we have:
Collect like terms
Substitute![Width = 55ft\ 6in](/tpl/images/2467/6342/ba4ab.png)
Convert inches to feet
Collect like terms
Divide both sides by 5
Hence:
An equation to find the value of b is:Read more about equations at:
