Answer:
Step-by-step explanation:
<u>Given system:</u>
<u>Substitute x into the second equation:</u>
- 10(y + 4) + 2y = 16
- 10y + 40 + 2y = 16
- 12y = -24
- y = -2
<u>Find x:</u>
Let us assume the width of the rectangle = w
Let us assume the length of the rectangle = l
Then
l = 2w
Also
Perimeter of the rectangle = 2 (l + w)
24 = 2 (2w + w)
24 = 2 (3w)
24 = 6w
w = 24/6
= 4 inches
Now
The length of the rectangle = 2w
= 2 * 4 inches
= 8 inches
So the length of the rectangle is 8 inches and the width is 4 inches.
