Question 119982
You add the 12 and the 24 to get 36. You can't combine that with the radical term. So the answer
to this problem is that the perimeter P of this triangle is:
.
{{{P = 12 + 24 + 12*sqrt(3) = 36 + 12*sqrt(3)}}}
.
And that's all you can do with it unless you want to find a "just about" answer. You could do
that by using a calculator to find the square root of 3. Then multiply that square root by 12.
Once you get that answer you add 36 and you get the answer of:
.
{{{P = 56.78460969}}}
.
But that's not the exact answer. It's very, very, very close to exact. The more accurate answer is:
.
{{{P = 36 + 12*sqrt(3)}}}
.
You were right ... you can't add the radical term directly to the integers.
.
Hope this helps you to understand the problem ...
