So I view this as a rectangle and 2 triangles.
To get the area of a rectangle, you do base × height.
To get the area of a triangle, you do (1/2)base × height
Let's do the rectangle first.
14 × 10 = 140in²
The area of our rectangle is 140in².
Now let's do the triangles.
(1/2) × 4 × 14 = 28
However, there are two triangles, so the area of both amount to 56in².
Now, we add the area of the triangles and the area of the rectangles.
140 + 56 = 196
The area of this trapezoid is 196in²
