Jen is carpeting a room. A drawing of the floor is shown. Look at the figure. A symmetrical trapezoid is shown. The trapezoid is divided into a square and two congruent right triangles by dashed lines drawn from the top vertices to the longer bottom base of the trapezoid. The side length of the square is labeled 4 meters. The heights of the triangles are labeled 4 meters. The bases of the triangles are each labeled 1 meter.

How much carpet will she use?

don't report but were is the digram

step-by-step explanation:

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.
