Question

The width of a rectangle is 33cm. The perimeter is at least 776 centimeters. Hat would the inequality be?

Answer 1

So, I'm assuming you need to find the inequality of the length of the rectangle. So, since we know the perimeter of a rectangle is:

`P = 2(l+w)`

And you are given the w (width), and also given that the perimeter's at least 776cm:

`772 \geq 2(33+l)`

We just solve for l:

`772 \geq 66+2l`

`706 \geq 2l`

`(706)/(2) \geq l`

`353 \geq l`

So your answer is:

`l \leq 353`
