The sum of the area of these three rectangles will be 3x² + 20x.

<h3>What is the area of the rectangle?</h3>

Let L be the length and W be the width of the rectangle.

Then the area of the rectangle will be

Area of the rectangle = L×W square units

The lengths and the widths of the following three rectangles are labeled.

The area of the first rectangle will be

A₁ = x · x

A₁ = x² square units

The area of the second rectangle will be

A₂ = 20 · x

A₂ = 20x

The area of the third rectangle will be

A₃ = 2x · x

A₃ = 2x²

Then the sum of the area of these three rectangles will be

A = A₁ + A₂ + A₃

A = x² + 20x + 2x²

A = 3x² + 20x

Thus, the sum of the area of these three rectangles will be 3x² + 20x.
