Step-by-step explanation:
You can use Heron's formula for this question.
Heron's Formula: Area of Triangle = root s (s-a) (s-b) (s-c)
Where s = perimeter/2 and a, b, and c are the side lengths.
So solving ...
s = perimeter/2
= (9yd + 3yd + 8yd) / 2
= 20yd/2
= 10yd
A = root 10yd (10yd-9yd) (10yd-3yd) (10yd-8yd)
= root 10yd (1yd) (7yd) (2yd)
= root 140yd
= 2 root 35
