Question

Maci put 200 inches of ribbon along the border of a rectangular bulletin board. If the links of the bulletin board is four times the width then what are the dimensions?

I need help finding the answer

Answer 1

Length:80 in. Width:20 in.

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.
