Express the area of the entire rectangle.
Expression should be expanded.

Answer 1

A = 14x^2 - 21: Area of rectangle

Explanation:

The area of a rectangle of width W and height H is A = WH.

If H = 7 and W = 2x^2 - 3, then the area of the rectangle is

A = (2x^2 - 3)(7), or

A = 14x^2 - 21: Area of rectangle
