You want to carpet a room that measures 10 feet to 12 feet, making an area of 120 square feet. but carpet is usually sold by the square yard. how many square yards of carpet do you need?

13.33 square yards.

Step-by-step explanation:

A square yard is a unit of area equal to the size of a square that is one yard on a side. It is equal to 9 square feet or about 0.836 square meters.

120/9=13.33.

Hope I helped!

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
