Answer:
2.5551872e+22
Step-by-step explanation:
Triangle
Area = 1/2 b * h
Area = 1/2*15 * 9 = 1/2 * 135 = 67.5
Rectangle
Area = b * h
Area = 15 * 4
Area = 60
Trapezoid
Area = (1/2) * (b1 + b2)* h
Area = (1/2) * (15 + 18) * 4
Area = 1/2 * 33 * 4
Area = 66
Total Area
Total Area = 66 + 60 + 67.5 = 193.5 Answer
Answer:
64 squnits
Step-by-step explanation:
trapezium is (base+top)/2 times height
(6+10)/2=8
8x8=64
Answer:
x=55
Step-by-step explanation:
The exterior angles of a polygon add to 360.
x+x+x+x+x+x+30 = 360
Combine like terms
6x+30 = 360
Subtract 30 from each side
6x+30-30 = 360-30
6x = 330
Divide by 6
6x/6 =330/6
x =55
