What is the area of the two rectangles shown below?

DedPeter [7]

Answers are in bold.

For the first one:

The total area of both shaded and unshaded portions is equal to $3x(4x+7)$ , which simplifies to $12x^2}+21x$ . The area of the middle white portion is $(5x)(2x)$ , which simplifies to $10x^2$ . To find the area of the shaded portion, we do $12x^2}+21x - 10x^2$ . Combining like terms, we get $2x^2+21x$ as our expression for the area of the shaded portion of the first rectangle.

For the second one:

The total area of both shaded and unshaded portions is equal to $6n(8n+14)$ , which simplifies to $48n^2}+84n$ . The area of the middle white portion is $10n(4n+1)$ , which simplifies to $40n^2+10n$ . To find the area of the shaded portion, we do $48n^2+84n-40n^2+10n$ . Combining like terms, we get $4n^2+94n$ as our expression for the area of the shaded portion of the second rectangle.
