To find the length of the rectangle, you can use the formula for the area of a rectangle:
Area = Length × Width
You're given that the area is 42 square meters, and the width is 6 meters. Plugging these values into the formula, you can solve for the length:
42 m² = Length × 6 m
Now, divide both sides of the equation by 6 to isolate the length:
Length = 42 m² / 6 m
Length = 7 meters
So, the length of the rectangle is 7 meters.
