Answer 1

Mr. Jenson needs 250 square tiles of dimensions 12 cm which cover 3.6 square metres walkway.

What is the area of Square?

The area of a square is the product of the length of each side with itself, i.e. Area A = s x s where s is the length of each side of the square.

Mr. Jenson wants to tile 3.6 sq. meters or 36000 sq. cm.

Total number of tiles is 250.

Area of tile = $\frac{Total covered area}{Number of tiles}$ = 36000/ 250    = 144 sq. cm

s X s = 144 sq. cm

s = $\sqrt{144}$ cm

s = 12 cm

Thus, Mr. Jenson needs 250 square tiles of dimensions 12 cm which cover 3.6 square metres walkway..
