We can start by plugging in the given length, l = 15, into the equation:
2 l + 2 w = 48
2(15) + 2 w = 48
30 + 2 w = 48
Next, we can isolate the variable w by subtracting 30 from both sides:
2 w = 18
Finally, we divide both sides by 2 to solve for w:
w = 9
Therefore, if Manny makes the garden 15 feet long, the width should be 9 feet in order to use all 48 feet of wood for the border.
Manny has 48 feet of wood. He wants to use all of it to create a border around a garden. The equation 2 l plus 2 w equals 48 can be used to find the length and width of the garden, where l is the length and w is the width of the garden. If Manny makes the garden 15 feet long, how wide should the garden be?
