Question

numeric 10 points
start with a 5 × 5 grid as pictured below.
what is the area of the entire grid?
answer

Explanation:

Step1: Recall the formula for the area of a square

The area of a square is \(A = s^2\), where \(s\) is the side - length.

Step2: Identify the side - length of the grid

The grid is a \(5\times5\) grid. So the side - length \(s = 5\) (assuming each unit square has side - length \(1\)).

Step3: Calculate the area

Substitute \(s = 5\) into the formula \(A=s^2\). We get \(A = 5\times5=25\).

Answer:

25
