Answer:

$407 yd^{2}$

Step-by-step explanation:

first find the area of the rectangle, which would be $16*13 = 208$ yd²

then find the arc length of the sector, which is about 30.6yd

use the arc length to find the area of the sector, which is about 199.09yd²

add together the area of the rectangle and sector:

199.09 + 208 ≈ 407
