Answer:
42.5
Step-by-step explanation:
Is this from khan? Meh, anyways, we need to find the area of the missing sides first.
The formula for area of a triangle is:
1/2(b×h)
So we multiply two and two and you get four. 2×2=4
Then you divide and that would be two. 4÷2=2
For the next one, you do the same.
You multiply five and two, which gives you ten. 5×2=10
Then you divide by two, which gives you five. 10÷2=5
Then you add the missing area lengths together to get a total of seven.
Then you would find the entire area. By that, I mean the whole thing.
I'm not sure if you noticed but the height of the missing triangle on the left is two.
2+3.5=5.5.
So that means that we have found out the entire height.
5.5×9=49.5
But that's not the answer. That's because the shape most certainly not a whole shape. It has some missing parts, if you see what I mean.
So that means that you have to subtract the area missing from the total area. That would be....
49.5 - 7 = 42.5
total missing actual
area area area
Answer:
36 cm²
Step-by-step explanation:
Add the bases, then multiply by the height
So it's
(2 + 4) 6
6 • 6
36 cm²
15(1.03)^x > 25
(1.03)x > 25/15
x ln 1.03 > ln (25/15)
x > 17.28
So the required year will be 2018
