The length of a rectangle is represented by the function l(x) = 5x. the width of that same rectangle is represented by the function w(x) = 2x2 − 4x + 13. which of the following shows the area of the rectangle in terms of x?

(l ⋅ w)(x) = 10x3 − 4x + 13
(l ⋅ w)(x) = 10x3 − 20x2 + 65x
(l + w)(x) = 2x2 + 1x + 13
(l + w)(x) = 2x2 − 9x + 13
