Since there are 4 sides in a rectangle, we'll divide 48 by 4
[tex] \frac{48}{4} [/tex] = 12
We know that the length is 6 feet longer than 2 times it width.
12 + 6 = 18
The length of one side of a rectangle is 18.
The total length of both sides is 36 because 18 + 18 = 36
48 - 36 = 12
The width of both sides of a rectangles is 12. Now if we divide 12 by 2 we'll get the width of one side of a rectangle..
[tex] \frac{12}{2} [/tex] = 6
The width of one side of the rectangle is 6.
The length of one side of the rectangle is 18.
Let's check and see if our answer is correct. We need to get a 48 as an answer since that's the perimeter of the rectangle.
2 × ( length + width )
2 × ( 18 + 6 ) = 48
Yay! We got it right!! Hope you understood this :)
