We can solve for the 3 triangle sides.
The left side is easy 6.
Second side² = 7² + 4²
Second side² = 49 + 16
Second side = square root (65)
Second side =
<span>
<span>
<span>
8.0622577483
</span>
</span>
</span>
Third Side² = 7² + 2²
Third Side² = 53
Third Side =
<span>
<span>
<span>
7.2801098893
</span>
</span>
</span>
When we know 3 sides, we use Heron's formula for calculating area:
Perimeter =
<span>
<span>
<span>
21.3423676376
</span>
</span>
</span>
Semi-Perimeter =
<span>
<span>
<span>
10.6711838188
</span>
</span>
</span>
Using Heron's Formula
area = square root (<span>10.6711838188 * </span><span>4.6711838188 * </span>
<span>
<span>
<span>
2.6089260705
</span>
</span>
</span>
*
<span>
<span>
<span>
3.3910739295
</span>
</span>
</span>
)
area = square root (441)
area = 21
Yes, it's just that "easy". LOL
You multiply each by four to get the next number.
2*4=8
8*4=32
32*4=128
The next one in sequence would be 512. Since 128*4=512
In An arithmetic sequence will add or subtract the same thing each time to find the next term. In this case we start with 10 and need to get to 40 on the 6th term. This is a difference of 30 that needs to be divided by 5 open spaces. You are adding 6 each time.
10, 16, 22, 28, 34, 40, _,_,_,_, 70, _,_,_,_,100,_,_,_, 124.
Another way to do this would be to look at the 5th term and multiply it by 4 to get to the 20th term. 34 x 4 = 124.
