Answer:
~4.7%
Step-by-step explanation:
Area of the rectangle: 35*52=1820
Area of 1 small circle: A=πr2=π·32≈28.27433
28.27433*3=84.82299
84.82299/1820=0.04660603846
Therefore, about 4.7%
The height is 5 m. The area of a trapezoid is (b1+b2/2)h
The length l is given as:
l = 2 w – 6
where w is the width
We know that the fencing is 30 feet therefore the
perimeter (excluding the side of the house) is:
P = l + 2 w = 30
2 w – 6 + 2 w = 30
4 w – 6 = 30
w = 9
So the length l is:
l = 2 (9) – 6
l = 12
<span>The dimensions are 12 ft x 9 ft</span>
