the area of the rectangle is 4x^2. whats does the coefficient 4 means in terms of the problem?

length is  4 times greater than breadth

Step-by-step explanation:

We know that , area of rectangle is given by

A=length*breadth ( equation 1)

given is A=4x^2

4x^2=(4x*x)

comparing with equation 1 we get ,

length=4x.

breadth=x.

hence  4 coefficient tell that length is 4 times greater than breadth.

a is the correct
