Answer: 393.75
<u>Step-by-step explanation:</u>
I am pretty sure it is the fourth choice, mThis is because 54+81=135 and angle YXW is 135°
perimeter = 2L+2W
L=2+w
40 = 2L+2W
40= 2(2+w)+2W
40=4+2w+2w
36=4w
w=9
L=9+2=11
2(9) = 18, 2(11) = 22, 22+18 = 40
L=11
W=9
Area = L x w
area = 11x9= 99 square yards
