Answer:
48.25
Step-by-step explanation:
When finding an area of a triangle it is area = base times height divided by 2.
AKA a =bh1/2
We can do that for all sides in this equation.
For the bottom we can do:
5*4.3=21.5 21.5/2 = 10.75
For one side we can do:
5*5 = 25 25/2 = 12.5
12.5 = one side, but there are three so,
12.5*3 = 37.5
37.5 + 10.75 = 48.25
