Find the area of this rectangle.

Then divide it by 200 to find the number of gallons needed.

The basement floor is a rectangle. The length and width are given in the problem.

ok so do i multiply the length times width or sumthing?
thank you

• geometry - ,

i got 25 times 40 equals 1000

• geometry - ,

Right. The area of the basement floor is 1,000 square feet.

Now, divide 1,000 by 200 to find the number of gallons needed.

You're welcome. And the more you work on math, the better you're understanding it.
