<h3>Answer:   63 meters</h3>

==================================================

Work Shown:

width = w

length = w+9

perimeter = 2*(length + width)

P = 2(w+9+w)

P = 2(2w+9)

P = 4w+18

4w+18 = P

4w+18 = 270

4w = 270 - 18

4w = 252

w = 252/4

w = <u>63 meters is the width</u>

w+9 = 63+9 = 72 meters is the length

Check:

perimeter = 2*(length + width)

perimeter = 2*(72 + 63)

perimeter = 2*(135)

perimeter = 270

The answer is confirmed.

What is the angle of the rotation from RST TO R'S'T'
zavuch27 [327]

Answer:

<em>-90 degrees</em>

Step-by-step explanation:

Draw a segment from the origin, point O, to point R. Draw a segment from the origin, point O, to point R'. The angle of rotation is the angle between segments OR and OR'.

The slope of segment OR is 2/3.

The slope of segment OR' is -3/2.

The slopes are negative reciprocals, so the segments are perpendicular.

The angle between the segments is 90 degrees. The rotation is counterclockwise, so it is a negative number of degrees.

The angle of rotation is -90 degrees.
