Answer:
50 inches
Step-by-step explanation:
Given that
5 equal sized square shelves arranged in a column.
Total area of five shelves = 500 sq inches
To find:
Length of shelving unit = ?
Solution:
First of all, let us find the area of each shelving unit.
Area of each shelving unit = Total area of five shelved divided by 5
Area of each shelving unit = 500
5 = 100 sq units.
Each shelving unit is of square shape and area of a square is given as:
Area = ![Side^2](https://tex.z-dn.net/?f=Side%5E2)
100 = ![Side^2](https://tex.z-dn.net/?f=Side%5E2)
So, side of shelve = 10 inches
Now, there are 5 squares in the shelving unit.
So, length of shelving unit = ![10 \times 5 = \bold{50 \ inches}](https://tex.z-dn.net/?f=10%20%5Ctimes%205%20%3D%20%5Cbold%7B50%20%5C%20inches%7D)
