Answer:
98 feet
Step-by-step explanation:
If it is similar that means the side lengths are scaled by a scale factor.
The original garage is 30 feet wide, this one is 35 feet. To find the scale factor, 35 / 30 = 1 . Multiply 12 by the scale factor and you get 14 feet as the length. To find the amount of rope to rope off the area, you find the perimeter. Perimter is 2 * length + 2 * width.
14 * 2 + 35 * 2 = 98

x = 80
the sum of the angles round a point is 360°
the 3 angles here must sum to 360°
3x + x - 27 + 67 = 360
4x + 40 = 360
subtract 40 from both sides.
4x = 360 - 40 = 320
divide both sides by 4
x = = 80
thus the 3 angles are 67°, 240° and 53°
