Garth estimated the heigh of the door to his claroom in meters what is reasonable estimate?

A reasonable measure for the height of the door would be 2.23 meters

Step-by-step explanation:

We use three units of measurement in our daily life.

Centimeter, Meter and Kilometer

When comparing the three units centimeter is the smallest unit and kilometer is the largest.

1 meter= 100 cm

1 kilometer= 1000 meter= 100000 centimeter

If we measure the height of the classroom's door  in centimeter which is approximately 223 cm, it is better to convert it into a unit higher than centimeter. We know that 100 cm is equal to 1 meter. So, instead of writing 223 cm it is better to write 2.23 m, neither 0.223 Km.  If the number lies between 100 cm ≤number <100,000 cm,  convert it into meters by dividing the number by 100, which is best unit of measurement.

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)
