Question

The area of a rectangle must be at least 153 square feet. If the length is 9 feet, find the minimum for the rectangle's width.

Answer 1

How do you find the area of a rectangle?

Answer 2

Length times width

Answer 3

So \(l\times w=area\), fill in what you know.

Answer 4

So it would be 9 times x right since we don't know the length

Answer 5

Exactly. That would also be equal to 153 since they give you the area.

Answer 6

So how do you find x?

Answer 7

9x=153, how do you isolate x?

Answer 8

I would divide right

Answer 9

Indeed you would, and your answer would be?

Answer 10

Hmm well I don't have a calculator with me so I'm stuck

Answer 11

How many times does 9 go into 15?
