Find and simplify an expression for the area of three rows of m squares with side lengths of m centimeters. Please help

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

(c)

Step-by-step explanation: Given that,

are two points contained in the function. Since it is a direct variation function, so it is a straight line passing through the given points.

Let,

So, slope of the line is given by

The equation of the line or the function is

Thus, (c)   is the correct option.
