Answer:81

Step-by-step explanation:

Area = length x width

You have the area and the length so plug those numbers in.

364.5=27w

Divide both sides by 27 to isolate the width.

13.5=width

To find the perimeter you multiply the length by two and the width by two then add them together.

Perimeter=2L+2W

2x27=54

2x13.5=27

54+27=81

------------------------------------
Area = 1/2 x 9 x 7.8
Area = 35.1 yd²

------------------------------------
Area of the 3 side triangles:
------------------------------------
Area = 3 [ 1/2 x 9 x 10 ]
Area = 135 yd²

------------------------------------
Total Area:
------------------------------------
Total Area = 135 + 35.1
Total Area = 170.1 yd²
