Each tile is 3/2 feet by 3/2 feet. There are 10 tiles on the bathroom floor.
Yuki888 [10]

9514 1404 393

Answer:

  22.5 square feet

Step-by-step explanation:

The area covered by one tile is the product of its dimensions:

  A = lw

  A = (3/2 ft)(3/2 ft) = 9/4 ft²

The area covered by 10 tiles is 10 times the area covered by one tile. The area covered is ...

  covered by tiles = 10 × 9/4 ft² = 90/4 ft²

  covered by tiles = 22.5 ft²

22 1/2 square feet is the area covered by tiles.

Answer:

Step-by-step explanation:

Amount paid for first 100 watches = (65% of 80) *100

                                                        =\frac{65}{100}*80*100\\\\= 65*80\\= 5200

Amount paid for next 50 watches = (55% of 80) * 50

                                                        = \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200

Remaining watches = 280 -(100+ 55)

                                 = 280 - 155 = 125

Amount paid for 125 watches = (45% of 80) *125

                                                  = \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500

Amount received by the watch maker = 5200 + 2200 + 4500

                                                               = £ 11900
