Answer:

[tex]2 {x}^{2} - 11x + 15[/tex]

Step-by-step explanation:

We we're given the length of the rectangle as

[tex]l = 2 {x} - 5[/tex]

and the width of the rectangle as :

[tex]w = x - 3[/tex]

Recall that, the area of a rectangle is

Area=l×w

We substitute the given dimensions of the rectangle into the formula to get:

[tex]area =( 2 {x} - {5} ) \times(x - 3)[/tex]

We expand

[tex]2 {x}^{2} - 6x - 5x + 15[/tex]

This simplifies to:

[tex]2 {x}^{2} - 11x + 15[/tex]
