Answer: Width of rectangle = 7 meters

Length of rectangle 7-1=6 meters

Step-by-step explanation: Let w (meters) be the width of the rectangle, then (w-1) (meters ) will be its length.

Now, we know that the area of rectangle is given by :-

Therefore, for the given rectangle , the area of rectangle will be

L = W -1

L * W = 42

L = 42 / W

substituting this into A

42 / W = W -1

Multiplying both sides by "W"

42 = W^2 -W

W^2 -W - 42 = 0

W = 7

Length = 6

Hence, the width of rectangle = 7 meters

Length of rectangle 7-1=6 meters
