The carpet Danil has chosen for his new recreation room costs $8.99 per square metre. this room measures 15ft by 18ft. how much
Fudgin [204]

Answer:

$225.50 (nearest cent)

Step-by-step explanation:

1 foot ≈ 0.3048 m

Width of room = 15 ft ≈ 15 x 0.3048 = 4.572 m

Length of room = 18 ft ≈ 18 x 0.3048 = 5.4864 m

Area of room = width x length = 4.572 x 5.4864 = 25.0938208... m²

Cost of carpet = $8.99 per m²

Total cost of carpet = 25.0938208 x 8.99 = $225.50 (nearest cent)

Answer the three questions pls
Mila [183]

3.60 divided by 12 is 0.3 or 30 cents. 5 divided by 20 is 0.25 or 25 cents. 6.40 divided by 32 is 0.20 or 20 cents
