Answer:

a = 132 ft^2

Explanation:

Area of triangle

a = (1/2)bh

---------------------------

Base

a = (1/2)(8)(6)

a = 24 ft^2

----------------------

Each side

a= (1/2)*(8)(9)

a = 36

All three sides

a = 36 * 3

a = 108 ft^2

-----------------------

Total area

a = 24 + 108

a = 132 ft^2
