The width of a rectangle measures
Airida [17]

Answer:

Option (1)

Step-by-step explanation:

Length of a rectangle = (5.9d + 8.3f) cm

Width of the rectangle = (7.3d + 2.2f) cm

Since formula to get he perimeter of a rectangle is,

Perimeter = 2(length + width)

                = 2[(7.3d + 2.2f) + (5.9d + 8.3f)]

                = 2(13.2d + 10.5f)

                = (26.4d + 21f) cm

Therefore, Option (1) will be the correct option.
