Finding the shaded area of a triangle

 In class, we have been learning about finding the shaded area of a triangle. It was hard to do but today it we got more help on it and I started to understand. The success criteria is a three-step problem

Here are the success criteria on how to do it:

1. Find the area of the rectangle which it times the length by the height

2. Find the area of the triangle, half the base (the base can be anywhere) then times it by the height it has to be perpendicular to the base 

3. Then subtract the 2 answers you have then you will have the answer done
