1 inch = 15ft 4/3 inch = 20ft
15*12 = 180 inches 20*12 = 240 inches
Total number of tiles = 180/6*240/6 = 30*40 = 1200 tiles
E is the answer.

Room area = 1 inch * [4][/3] inch = (1 * 15) * ( [4][/3] * 15) feets = (15 * 12) * ([60][/3] * 12) inches = (15 * (2*6)) * ([60][/3] * (2*6)) inches = (30 * 6 * [120][/3] * 6
each 6 is a tile = (30 * [120][/3]) = 1200

1 inch = 15 feet 4/3 inch = 20 feet. Convert to inches now => 15*12=180; 20*12=240. So, we are getting 180 by 240 or 30(180/6)*40(240/6)=1200 (E)

Solution Given:• Dimensions of the rectangular floor = 1 inch by 1 \(\frac{1}{3}\) inches
o 1 inch = 15 feet o 1 feet = 12 inches
To find:• The number of square tiles 6 inches on a side will be needed to cover this floor. Approach and Working:• Dimensions of the rectangle in feet= 1* 15 feet by \(\frac{4}{3}\) * 15 feet = 15 feet by 20 Feet • Dimensions of the rectangle in inches = 15* 20 inches by 20 * 12 inch = 180 inches by 240 inches Area of the floor = 180* 240 • Total number of square tiles of side length 6 inches need to cover this floor = \(\frac{180 * 240}{6 * 6}\) • Hence, the correct answer is option E. Correct Answer: E

PS40602.01 OG2020 NEW QUESTION If the scale of the drawing is 1 inch = 15 feet, then the room has dimensions of 15 ft by 20 ft. Therefore, the area of the room is 15 x 20 = 300 sq. ft. Since each tile is 1/2 x 1/2 = 1/4 sq. ft, we need 300/(1/4) = 300 x 4 = 1,200 tiles to cover the floor of the room. Answer: E

E is the answer. Not the smartest question but why are we taking both the cases? the other one is just a scale, right?

Convert the drawing from inches to feet and you end up with a rectangle that is 20ft by 15ft each tile is 6 inches or 1/2 ft 20ft/ 1/2ft per tile = 40 tiles 15ft / 1/2ft per tile = 30 tiles 40*30 = 1200
