<u>Answer</u>
B. Length = 37, width = 28
<u>Explanation</u>
Let the length of the rectangle be x,
width is 9 less. So, width = x - 9
Perimeter of a rectangle = 2(length + width)
2(length + width) = 130
2(x + x - 9) = 130
2(2x - 9) = 130
4x - 18 = 130
4x = 130 + 18
4x = 148
x = 148/4
= 37
<em>Length = 37</em>
<em>Width = 37 - 9 = 28</em>
