The perimeter of room is 94 feet
Solution:
The formula p=2l + 2w gives the perimeter p of a rectangular room with length l and width w
A rectangular living room is 26 feet long and 21 feet wide
Therefore,
length = 26 feet
width = 21 feet
To find: perimeter of room
Given formula for perimeter is:
p = 2l + 2w
Substituting the values in above formula
p = 2(26) + 2(21)
p = 52 + 42
p = 94
Thus perimeter of room is 94 feet
