Question

Write an expression to represent the area of the following figure.

X - 12
х
Your answer:
4x - 48
4x - 24
x² - 12

Answer 1

`x^2 - 12x`

Explanation:

The given rectangle had a length (l) of (x - 12), and a width (w) of x.

Area of rectangle =
`l * w`

Therefore, the expression representing the are if the given rectangle is:

`Area_(rectangle) = (x - 12)*x`

`Area_(rectangle) = x*x - 12*x`

`Area_(rectangle) = x^2 - 12x`

The expression for the area =
`x^2 - 12x`
