we are given

dimensions of rectangle as

length of rectangle is

[tex]L=2x+5[/tex]

width of rectangle is

[tex]W=x-2[/tex]

now, we can use formula of area of rectangle

[tex]A=L*W[/tex]

we can plug values

we get

[tex]A=(2x+5)*(x-2)[/tex]

now, we can simplify it

[tex]A=2x^2-4x+5x-10[/tex]

[tex]A=2x^2+x-10[/tex]..............Answer
