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
