Answer:

side 1: 1.6

side 2: 2.3

side 3: 2.6

Step-by-step explanation:

side 1: 2x - 3

side 2: x

side 3: 2/3(x + 2x - 3) = 2x-2

(2x - 3) + x + (2x - 2) = 6.5

5x - 5 = 6.5

5x = 11.5

x = 2.3

side 1: 1.6

side 2: 2.3

side 3: 2.6

Kazeer [188]

Answer:

Area = 209.5 ft² (nearest tenth)

Cost = $505 (approximated)

Step-by-step explanation:

Step 1: convert the inches to be in feet by dividing length in inches by 12.

17 feet 10 inches => 17 + \frac{10}{12} = 17.83 ft

11 feet 9 inches => 11 + \frac{9}{12} = 11.75 ft

Step 2: Find the area of the floor of the dinning room

Area = 17.83*11.75 = 209.5 ft² (nearest tenth)

Step 3: Find the cost of the work.

Cost = 209.5 ft² × $2.41 = $505 (approximated)
