First you need to find a way to cut it into regular shapes.
I would make a small square with the top part, and a bigger rectangle with the bottom part.
Find the areas of the two shapes separately.
The area of the bottom rectangle is 6x8=48inches.
To find the area of the top square you need to find the height by subtracting 10-6=4inches.
Then multiply 4x4=16inches.
Now that you have the area of the two shapes, add them together.
16+48=64inches.
The area is 64 inches.
