Question

Robert builds a rectangular deck with a length that is four less than two times the width of the deck.

Write the equation for the area of the deck, where w is the width.

Answer 1

Let

• Width be w
• Length=2w-4

Now

`\\ \sf\longmapsto Area=Length* Breadth`

`\\ \sf\longmapsto Area=w(2w-4)`

`\\ \sf\longmapsto Area=2w^2-4w`
