Okay. So as you probably know, area is l * w. 10 * 5 is 50, so the original area is 50 square feet. With each side being increased equally, after that is done, the area is 84 square feet. If you know basic multiplication, 12 * 7 is 84. 12 - 10 is 2. 7 - 5 is 2. That number being added is the same for all sides. The amount added to each side is 2 feet.

The area of a rectangle with width × and length 7× is 7². what does the coefficient 7 mean in terms of the problem?

tatuchka [14]

The coefficient 7 means that the length is 7 times the width

<h3>How to interpret the coefficient?</h3>

The given parameters are:

Width = x

Length = 7x

Area = 7x^2

We have:

Length = 7x

Substitute Width = x in Length = 7x

Length = 7 * Width

This means that the length is 7 times the width
