Given:

The area model.

The area of the shape is 82 square units.

To find:

The correct equation for the given situation.

Solution:

We know that, area of a rectangle is

Area=Length \times Width

The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is

A_1=(x)\times (3x)=3x^2

A_2=(x)\times (4)=4x

A_3=(3)\times (3x)=9x

Now, the total area is equation to 82 square units.

A_1+A_2+A_3=82

3x^2+4x+9x=82

3x^2+13x=82

Since the required equation is 3x^2+13x=82, therefore, the correct option is C.

The area of a rectangular wall of a barn is 133 square feet. It's length is 12 feet longer than the width. Find the length and w
GuDViN [60]
I'll give you a few hints. Area of a rectangle is length times width. We know that length times width is 135 sq ft, so we can express it as: 

<span>L * W = 135 </span>

<span>Now, L is 6 feet longer than width (L = 6 + W). Something tells me this is going to involve a quadratic formula then plugging in values into our original equation. </span>
