The scale factor's 3 since 12 and 4 can be divided by 3 and -6 and -2 can also be divided by 3.
Answer:
15 feet
Step-by-step explanation:
Since this is a square the sides are of the same length.
Now the side multiplied by itself gives 225. Hence the length of the side is a number which multiplied by itself gives 225. It is easy to see that 15 × 15 = 225. Therefore the side is 15 feet long.
The slope of the line is -1/7, so the perpendicular line has a slope of 7
