I assume by lateral area that you are looking for the areas of the pyramid without it's base. You need to calculate the area of the three sides and add them up.

Using the Pythagorean theorem, \[10^2=6^2+x^2\]Solve for x.
OpenStudy (anonymous):
okay so it would be 100 = 36 plus what
OpenStudy (pfenn1):
Rearranging the equation\[100-36=x^2\]\[x^2=64\]x=8
OpenStudy (pfenn1):
Now, you use the equation for the area of a triangle\[A=\frac 12bh\] where b is the base length and h is the height
OpenStudy (pfenn1):
A times 3 because there are 3 triangles.
