Finding area (of a triangle),

The area of any shape in the inside of it, which means that you will be finding the measurements of the shape's insides/ Do not confuse this for volume change, those are for three-dimensional figure.
The formula to find the are of any rectangle or square is A=BH
(Area equals base multiplied by the height). Though it is different for Triangles. Since some triangles are half of a square, the formula is A=BH(1/2)
(Area equals base times height, divided by half OR two). It is easier to remember this because you have to divide the new area by two which gives you the new area. Remember to always divide.

Doing the inverse.

Sometimes a problem will ask you to do the inverse operation meaning that you will be trying to find another variable to the problem. So instead of locating the are, they will already give it to you and you will have to find the base or the height.
So if the area of a shape is 14, the base is 2. Then you will multiply two by 14, giving you 28. Then you divide two (which i the base) by 28 and your height is 14!

A trick is you should always remember to multiply by two first so you will not get confused.

Later days!
