Question

the length of a rectangle is 9 feet more than the width . if the perimeter is 174 feet, what are the length and the width

Answer 1

x + x + x + 9 + x + 9 = 174

Answer 2

x is the length of the width, and since the length is 9 more than the width, it would be x + 9

Answer 3

So you have a rectangle that looks like this.


Since the perimeter is just 2w+2l, you can write an equation.

P=2w+2l
Now plug in your details. We know that P is 174 feet.
174=2w+2l
We know that the length is (w+9) and the width is just w. Plug those in.
174=2w+2(w+9)
Now solve this.
