The area of a traingle is 
So we need to know the base and the height
To work out the sides of a right angle triangle we can use a²+b²=c
c is the hypotenuse and a and b are the other sides
Because this triangle is isoceles we know that a and b are the same
a²+b²=c²
a²+a²=c²
2a²=c²
2a²=(x√6)²
2a²=(x√6)(x√6)
2a²=x²+x√6+x√6+6
2a²=x²+x√6+x√6+6
a²=

Hi!
We can solve this by setting up a proportion
Solve for x by cross multiplying.
19 x 60 = 1140
1140/38 = 30
You can type 30 words in 60 seconds
Hope this helps! :)
