Question

Write an expression for the area of a rectangle with length 2x and

width x.
The area of a rectangle with that length and width would be?

Answer 1

area of the rectangle =

`{2x}^(2) {cm}^(2)`

Explanation:

length = 2x

width = x

area of the rectangle = length × width

`a = l * w \\ a = 2x * x \\ a = {2x}^(2)`
