Answer:Width = 7 units

Step-by-step explanation:Length = x units

Width = (x -1) units

Area = 56 square units

length * width = 56

x * (x – 1) = 56

x*x – x*1 = 56

x² – x – 56 = 0

x² -8x + 7x – 7*8 = 0

x(x – 8) + 7(x – 8) = 0

(x – 8)(x + 7) = 0

Here, (x +7) is ignored because measurement will not in negative.

x – 8 = 0

x = 8

Length = 8 units

Width = 8-1 = 7 units
