Answer:
Area of the shaded area = 60 m^2
Step-by-step explanation:
Remark
I don't think you need the 40 degrees for anything.
Formula
Area of Shaded part = area of the rectangle - area of the triangle
Solution
<u>Area of the Rectangle</u>
L = 12 meters
W = 10 meters
Area = 12 * 10
Area = 120 m^2
<u>Area of the triangle</u>
Area = 1/2 b * h
b = 12
h = 10
Area = 1/2 * 12 * 10
Area = 120/2 = 60
Area of the shaded area
120 - 60 = 60
Perimeter of Figure = Perimeter of 2 semicircles + Measures of two straight line
P = 2(πr) + 2*x
P = 2*3.14*7 + 2*13
P = 43.96 + 26
P = 69.96 m
In short, Your Answer would be: Option C
Hope this helps!
Answer:
BH = 2
Step-by-step explanation:
The altitude divides the triangle into similar triangles. The ratio of the long side to the short side is the same for all, so ...
AH/BH = BH/HC
4/BH = BH/1
4 = BH² . . . . multiply by BH
2 = BH . . . . . take the square root
