Answer:
3m²
Step-by-step explanation:
A square is quadrilateral (four sides) in which all sides are equal. Also, opposite sides are parallel to one another and all the four angles in a square are 90 degrees each.
The area of a square is given as:
Area = length * length
Given that the square has side lengths of m centimeters, therefore:
The area of each square = m cm × m cm = m² cm²
There are three rows of m squares, hence the total number of square is:
Total square = 3 rows * m squares per row = 3m squares
The total area of the square = area of each square * total number of square = m² * 3m = 3m² cm²
What's right? i dont see any thing
