Question

An original rectangle has a length of fourteen and a width of twelve. What happens to the area if the new width is three times the original width?

Answer 1

Recall the area of the rectangle.

A = lw

A = (14)(12)

A = 168 units²

Tripled...

A = l(3w)

A = (14)(3)(12)

A = 504 units³

If you triple the width, then you also triple the area because they are directly proportional to each other.
