Answer:
18 cameras will be necessary to cover the entire store.
Step-by-step explanation:
Length of the store= l = 48 feet
Width of the store = w = 48 feet
Area of the store , A= l × w = [tex]48 feet\times 48 feet = 2,304 ft^2[/tex]
Area covered by single camera , a= [tex]128 ft^2[/tex]
Let the n number of cameras are required to cover the store .
[tex]n=\frac{A}{a}=\frac{2,304 feet^2}{128 feet^2}=18[/tex]
18 cameras will be necessary to cover the entire store.
