Ahh ok so split it up into two rectangles:

Rectangle one:
A=lw
A=4(12)
A=48

Rectangle two:
A=lw
A=10(2)
A=20

Add both areas up to get 68 ft squared!! :)

Answer:

68 square feet.

Step-by-step explanation:

My way of doing it is to first, split the shape where the length is different so it would be easier to solve. That means you should have the bottom part of the shape split from the whole shape, which makes 2 rectangles. The bottom rectangle should have the length of 2 feet, and the width of 10 feet on both parallel sides. The top rectangle should have the length of 4 feet, and the width of 12 feet on both parallel sides.

Next, you multiply both rectangles by their width and length. For example,  first start with the first rectangle on the top. You should multiply the length, 4 feet by the width, 12 feet. Then, for the bottom rectangle, multiply the length, 2 feet by the width, 10 feet.

1.)  4 x 12 = 48

2)  2 x 10 = 20

Lastly, add the two numbers to get the answer.

48 + 20 = 68
