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!
It is often called a straight-edge.
a ruler no LITERLY
You can measure it with a ruler.
a ruler or a tpe measure
get a tape measure or a ruler and measure it
use a ruler lol
To find the density of a rectangular solid with just a ruler, you would need to measure the length, width, and height with the ruler. Then, calculate the volume by multiplying the three measurements together. Finally, divide the mass of the rectangular solid by the volume to find the density.
with a ruler. You just have to do it along the side and not up the line
Use a ruler

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!
