Answer:
The perimeter of the kitchen wall = 60 b
Step-by-step explanation:
The number if tiles used in the length side of the square walk = 5 tiles
The length of 1 tiles = 3 b
So, the length of 5 tiles = 5 x ( Length of 1 tile)
= 5 x (3 b) = 15 b
So, the length of the square walk = 1 5 b
Perimeter of SQUARE = 4 x SIDES
⇒ Perimeter of the wall = 4 x (Side)
= 4 x (15 b) = 60 b
Hence, the perimeter of the kitchen wall = 60 b
