that is it
Answer:
336 ft^2
Step-by-step explanation:
All you have to do is find the area of each face, and add them up.
Firstly lets starts with the identical triangles.
There are two of them, and the area of a triangle is b*h/2
So the area is 6*8/2 , which is 24, and since their are two of them, we add another 24, and we get 48 so far.
Since all the other sides are rectangles, we can just multiply the given lengths and add them up.
So, we have
12x10, which is 120,
12x8, which is 96, and
12x6, which is 72.
Now add all of them up.
48+120+96+72 which is 336
Your answer is 336 ft^2
1/5, 0.4, 1/2, 0.75 is in order from least to greatest
The one all the way to the left matches with 1/7
1/18 matches with 0.05
0.5 matches with square root of 0.25
2/3 matches with 0.6
That's all I can help with.
