Answer:
20.9 yd
Explanation:
In order to find the area of a triangle you must multiply the base and the height together, then multiply that product by 1/2.
A = 1/2bh
Base: Bottom of a shape
Height: Distance between the bottom of a shape, or base, to the top of a shape
The base given is 11 yd.
The height given is 3.8 yd.
A = 1/2(11 x 3.8)
11 x 3.8 = 41.8
1/2 x 41.8 = 41.8/2 = 20.9
