Cynthia Besch wants to buy a rug for a room that is 21 ft wide and 30 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 360 square feet of carpeting. What dimensions should the rug have?

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

y=35

x=5
