A-length
b-width
perimeter of rectangular floor: 2a+2b=204
<span>The length is two times the width: a=2b
</span>2a + 2b = 204
2*2b + 2b = 204
6b = 204|:6
b = 34
a=2b=2*34=68
a=68->length
b=34->width
Answer:
<h2>
(9, -4) no</h2><h2>
(8, 6) yes</h2><h2>
(-1, -3) no</h2><h2>
(-2, 8) no</h2>

<em>we can write it like: </em>
<em>(8, y)</em>
<em />
<em>the only ordered pair that fits in here is the second one, that is (8, 6) the rest don't</em>
<em>thus the answer is such:</em>
(9, -4) no
(8, 6) yes
(-1, -3) no
(-2, 8) no
