Marina wants to install security cameras in her store, which has dimensions 48 feet by 48 feet. each camera can view an area of approximately 128 ft2, with a viewing area shaped like a right triangle.

the distance between grid lines is 4 feet.

how many cameras will be necessary to cover the entire store?

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 =

Area covered by single camera , a=

Let the n number of cameras are required to cover the store .

18 cameras will be necessary to cover the entire store.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
