Find the area of these shapes AND explain your method <br> Can some one help me :((

-Dominant- [34]

Answer:

Triangle - 21 units

Trapezoid - 65 units

Step-by-step explanation:

Because this triangle and trapezoid are reflections of each other when split in half, remove the highlighted parts to make them a rectangle. When made into a rectangle, you can use the formula length * width to find the area of either shape (trapezoid or triangle).
Note you won't be able to do this when solving for the area of ALL trapezoids and triangles.
