Answer:
296 inches
Step-by-step explanation:
The perimeter is the sum of sides of a rectangle
As the length is in feet while the width is in inches, a unit conversion must take place
As 1 feet equals to 12 inches
9 feet would be equal to 12*9=108 inches
The perimeter of a rectangle= 2(width)(length)
= 2(108)(40)
=296 inches
