The width of a rectangle measures (9h 1) centimeters, and its length measures (2h – 4) centimeters. Which expression represents the perimeter, in centimeters, of
the rectangle?
0-2 + 8h
0-10 + 22h
Submit Answer
16h - 4
0-5 + 11h

(22h - 8) centimeters

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

= 2{(9h - 1) + (2h - 4)}

= 2(9h - 1 + 2h - 4)

= 2(11h - 4)

= (22h - 8) centimeters

z-score = 0.741

Step-by-step explanation:

The provided information are:
