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.
