Let us divide our given image in several parts and then we will find area of different parts.
First of all let us find the area of our red rectangle with side lengths 6 units and 7 units.



Now let us find area of yellow triangle on the top of red rectangle. We can see that base of triangle is 6 units and height is 1 unit.



Let us find the area of green triangle.


Now we will find the area of blue triangle, whose base is 6 units and height is 2 units.


Let us add all these areas to find the area of our figure.



Therefore, area of our given figure is 54 square units.
1 hour = 60 minutes.
Divide the number of words per hour by 60:
86 / 60 = 1.433333
Rounded to the nearest tenth = 1.4 words per minute.
So what she wrote down is zx2x4 but you can simplify that to zx8 which then can be simplified to 8z. Which is the answer
