## Answer :

b-width

perimeter of rectangular floor: 2a+2b=204

The length is two times the width: a=2b

2a + 2b = 204

2*2b + 2b = 204

6b = 204|:6

b = 34

a=2b=2*34=68

a=68->length

b=34->width

Let width be x and length be 2x.

204 ft = 2(2x+x)

204 ft = 2(3x)

204 ft = 6x

204/6 = x

34 = x

therefore, width (x) = 34 ft

length (2x) = 2(34) = 68 ft
