The lateral area is the area of everything but the base. A shortcut formula for this area is Ph. (where P is the perimeter of the base and h is the height of the prism).
So the lateral area is (3+9+9.49)x37 = 795.13 m^2 or 795 m^2
The surface area is the lateral area plus the area of the 2 bases. The base is a triangle. (area = 1/2 bh)
Since there are two identical bases, the total area of the base is just 3x9 = 27
So the surface area is 795.13 + 27 = 822.13 m^2 or 822 m^2.
Answer:
e=30
k=15/2
h=90
Step-by-step explanation:
3e=60
e=30
30+4k=60
4k=30
k=15/2
15/2+2h=30
2h=45/2
h=90
Answer:
BC is equal to 7
Step-by-step explanation:
18 = 2x + 4
18 - 4 = 14
14 = 2x
14/2 = 7
7 = x
Since the number of days in July and in August is the same, there is no need to work out on the total number per month.
The mean number of people per day in August = 160 + 20 = 180
Answer: 180
