Answer:
90 feet
Step-by-step explanation:
==>Given:
Rectangular room measuring 21 feet by 23 feet
==>Required:
Perimeter of the room = the length of all sides of the room
==>Solution:
Using the formula P = 2L + 2W, we can find the perimeter of the rectangular room assuming that length big the room (L) = 23 ft, while the width (W) = 22 ft.
Therefore,
P = 2(23) + 2(22)
P = 46 + 44
P = 90 ft
Perimeter of the room = 90 feet
