how many 0.5-foot tiles are needed to completely cover a 4-foot square wall ? with steps

Question

SHOW THE STEPS !!

Answer 1

(1) Compute the total area to be covered by tiles.

 

A = 4 ft x 4 ft = 16 ft²

 

(2) Compute the area of a single tile.

 

a = 0.5 ft x 0.5 ft = 0.25 ft²

 

(3)  Divide total area to be covered by the area of a single tile to get the number of tiles required.

 

A/a = (16 ft²)/(0.25 ft²) = 64 tiles

Answer 2

8 rows (4 / 0.5 = 8!)

by

8 rows (4 / 0.5 = 8!)

 

8 x 8 = 64

Answer 3

Assume 4ftx4ft wall

Answer= 64 tiles

 

Step1

6in x 6in = 36 in²

48in x 48in = 2304 in²

 

Step2

(2304 in²) /(36 in²) = 64 tiles  Answer

 

 

get 70 in case some break...
