Answer:
633 yd^2
Explanation:
Alright, with this, lets divide it into 2 rectangles to make it manageable.
First, lets make a large rectangle at the bottom of the upside down L, with the sides 21 yd and 16 yd.
This will give you the area of 336 yd^2, by doing L*W.
Next, lets get the remainder of this figure. The height left is with the side length 9 yd and the width is seen on top side of the shape, being 33yd.
This part will be 297 yd^2, after multiplying.
Last, combine these two values using addition to get:
633 yd^2
