You must apply the following formula to calculate the area a triangle:
A=bxh/2
b=12 inches (the base of the triangle)
h=12.5 inches (the height of the triangle)
When you substitute these values into the formula, you obtain:
A=bxh/2
A=(12 inches)(12.5 inches)/2
A=75 inches²
<span>
You already have the area of one triangle. So, you only have to multiply this area by 7, because the seven (7) triangles are congruent, which means that they have the same area:
</span>
At=Ax7
At=(75 inches²)(7)
At=525 inches²
<span>
What is the area of the 7 sided figure?

The answer is: 525 inches²
2h+3
I feel that thats too easy
2867.5 is bigger
Even though they both show 5 numbers, the second one has only one decimal place versus 2 on the first
If you ignore the decimal, your left with
290 vs 2867
2867 is much bigger than 290 so this is the answer
They will higher 15 meters thank when they first started.
Answer:
The answer is c. 8 hours
Step-by-step explanation:
Since her battery dropped 25% in 2 hours then for it to drop 100% would take 8 hours.
25%+25%+25%+25%= 100%
so with this logic
25%= 2 hours
2+2+2+2=8
Hoped this helped !
