Step by Step Solution
Step 1
The picture below shows the square:.
Step 2
To calculate the area, we can start with the formula for the area of a square:
Step 3
Since the length of each side is given as 5cm, we can substitute
r
with 5. After doing so, we can calculate for
A
, as shown below:
Step 4
Now, the calculated number
25
only has meaning if we include the unit for it. Since the given length is in cm, the unit for area will be cm
2
. Hence:
A = 25 cm
