The measure of the space inside a 2d figure is called

an area

Step-by-step explanation:

A two-dimensional (2D) figure is like drawing on a sheet of paper. It has some width and some length, but no height.

So, you cannot calculate its volume, since it has only 2 dimensions, a volume requires 3 dimensions.

The only spacial measure you can do on a two-dimensional figure is its area (basically length * width, if we talk about a rectangle, other forms have different calculation methods).

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
