I need help finding the answer

Answer 1

Answer:

Length:80 in. Width:20 in.

Step-by-step explanation:

We know that the equation for perimeter is P=2L+2W.

We can make length 4W since it is four times the width.

The equation becomes 200= 2*4W+2W

                                       200=8W+2W

                                       200=10W

                                       ÷10    ÷10

                                        20=W

We know the width is 20 in. now so to find length multiply by 4.
