Question

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?

Answer 1

P=2L+2W
P=2(26)+2(21)
P=52+42
P=94

Answer 2

Perimeter = 94 feet

Explanation:

The formula for perimeter is

`P=2L+2W`

where, L is the length of rectangular room and w is the width of the room.

It is given that the dimensions of a rectangular room are

Length = 26 feet

Width = 21

Substitute L=26 and W=21 in the given formula.

`P=2(26)+2(21)`

`P=52+42`

`P=94`

Therefore, the perimeter of the room is 94 feet.
