Answer: The patio is 9 meters wide.
Step-by-step explanation:
Using the formula for the perimeter of a rectangle, we can find the width.
Formula:
P = 2L + 2W
Substitute known values:
42 m = 2(12 m) + 2W
Multiply:
42 m = 24 m + 2W
Subtract 24 m from both sides of the equation:
18 m = 2W
Divide both sides of the equation by 2:
9 m = W
