The perimeter of a park is 20.1208 km.

Side A is 4.0491 km shorter than side B.

How long are sides A and B?

Given that the park is a rectangle and has 4 sides

side a = 3.00565 side b = 7.05475

i got this by using this equation:

2 (x+4.0491) + x = 20.1208 to solve first divide each side by 2

(x+4.0491) + x = 10.0604

then combine x's

2x+4.0491=10.0604

then subtract 4.0491 on each side

2x = 6.0113

then divide each side by 2

* = 3.00565

that gives you side A

to find side B take side a + 4.0491

3.00565 + 4.0491 = 7.05475

and that is side B

5,000 of coarse because times them both and get ur answer
