• A. 250
• B. 255
• C. 450
• D. 200

Answer 1

The correct option is A

250

Given, side of square tile = 8 inches

$\therefore$ Area of the square tile = 8 x 8
= 64 sq inches

Number of tiles needed

=$\frac{\text{Area to be covered}}{\text{Area of one tile}}$

= $\frac{200\times 80}{8\times 8}$

= 250 tiles
