Answer:
10 inches
Step-by-step explanation:
Assuming that by 'deep' you mean length, we can set up a simple algebraic expression to solve this problem. We know that a rectangle has 4 sides, 2 of them equal sides, and all of those sides added up equals the perimeter. To say that algebraically, [tex]2a+2b=p[/tex]. We can fill in the blanks on this equation to solve.
[tex]2(27)+2b=74\\\\54+2b=74\\2b=20\\b=10[/tex]
The length of the other side is 10 inches.
Hope this helped!
