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. what is the perimeter of the room?

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
