The area of a rectangle is given by its length multiplied by its width. So that the expression that represents the area of the rectangle in the given question is [tex]\frac{3}{2}[/tex] [tex]x^{2}[/tex] squared unit.
A rectangle is a figure that has four straight sides, in which opposite sides are equal.
The area of a rectangle can be determined by the expression;
Area = length x width
Thus considering the given question, the length of the rectangle is tribble to that of the square. And the width of the rectangle is half of that of the square.
So that;
length = 3x
width = [tex]\frac{x}{2}[/tex]
Thus,
Area = length x width
= 3x ([tex]\frac{x}{2}[/tex])
= [tex]\frac{3}{2}[/tex] [tex]x^{2}[/tex]
Therefore, the area of the rectangle is [tex]\frac{3}{2}[/tex] [tex]x^{2}[/tex] squared unit.
