use a yard stick
where can you find a ruler that is 3 feet long?
No, a ruler is used only to measure length, width or height. You must use a protractor in order to measure the degrees in an angle.
only solids have "lateral area". triangles have "area". the area of a scalene triangle is given by heron's formula. height not needed.
The easy way to find the length of a pencil is to use a ruler to measure it. A "small" ruler might not make it, but a "regular" one foot ruler will do the job nicely.
Use a tape measure!

You find the height by using Pythagoras' theorem and then 0.5*base*height = area.
You don't. If you don't have the height, you can't do it.
Measure it!
try to use a ruler or you can make little squares next to it
