Final answer:

To find the area of a rectangle in polynomial standard form, we multiply the length and width. In this case, the area is 4x^2-16x+25.


Step-by-step explanation:

The area of a rectangle is found by multiplying its length and width. In this case, the length is (2x+5)(x-1) and the width is (2-3x). To find the area, we use the distributive property to multiply the length and width:

Area = (2x+5)(x-1)(2-3x)

To simplify this expression, we can use the FOIL method to multiply the first terms, outer terms, inner terms, and last terms:

Area = (2x^2-2x+5x-5)(2-3x)

Continuing to simplify, we combine like terms:

Area = (2x^2+3x-5)(2-3x)

Finally, we can use the distributive property again to multiply:

Area = 4x^2-6x-10x+15x+25-15x

Combining like terms once more, we have:

Area = 4x^2-6x-10x+15x+25-15x = 4x^2-16x+25

Therefore, the area of the rectangle in polynomial standard form is 4x^2-16x+25.
