The formula for perimeter is 2L + 2W and the formula for the area is L * W, since we don't know the width we will divide 35:7 = 5 and he the measurement for the width.
Now just add L + W = 12 and multiply by 2 the answer is 24
Or 2 * 7 + 2 * 5 = 24
8 feet
If 1 inch is 4 feet, multiply 4 times 2, and you will get 8.
Tenth: 243.9
Hundredth: 243.88
Ten: 240

The answer is 36°
Hope that helps, Good luck! (:
