Question

Jacob is tiling his square walk with square tiles. He is able to fit 5 tiles up and 5 tiles across. If each tile has a length of 3b, what is the perimeter of the wall?

Answer 1

The perimeter of the kitchen wall = 60 b

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
