Question

Kill’em Dead Pest Control sets out 1 super roach motel per 10 square feet. In a rectangular studio apartment that is 15 ft by 14 feet wide, about how many super roach motels will be set out?

Answer 1

First find the area of the rectangular studio apartment
Multiply the length and width together. It gives you the dimensions, 15 ft by 14 ft

Now divide by 10

Because in the whole area, we're setting up one trap for every 10 square feet

And that's how you'll find how many traps you'll be setting out
