The area of a rectangle is length * width, so we have:

A = 290 * 150

A = 43,500 sq ft.

Now, to find the number of bags needed for a 300 square feet per bag of fertilizer, we have:

Bags Needed = Total Square Feet of Lawn / Square Feet covered per bag

Bags Needed = 43,500 / 300

Bags Needed =

**145**
