Question

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

Answer 1

6x7=42cm squared
Base x height = triangle area
10+18=28/2=14
14x5=70cm squared
Add the parallel line together and divide that number by 2 then times that number by the height.

Answer 2

Triangle - 21 units

Trapezoid - 65 units

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.
