Without using a protractor, you can determine whether the angles are right angles by measuring the length of the diagonal and applying the converse of the pythagorean theorem. the length of both diagonals for each lateral side is 13 centimeters. from this, can you prove that the lateral sides are rectangles? why or why not?

answer: 323 is how many she has ☃☃⛄❄

step-by-step explanation:

8/k

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.
