Une voile « australienne » (très utilisée dans ce pays) permet de faire de l’ombre. Elle est commercialisée en deux modèles triangulaires dont voici les
dimensions :
• Modèle 1 : 2 850 mm, 2 200 mm, 3 600 mm
• Modèle 2 : 3 200 mm, 3 360 mm, 4 640 mm
L’un de ces modèles est-il un triangle rectangle ?

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

you would need to also lose 1 point for each of the other outcomes for it to be fair.
