Answer:
80 + 16 sqrt 13
Explanation:
in order to find the L.A, you have to find the perimeter of the base and then multiply it by the height.
You need to use the pythagorean theorem to find the missing side of the base:
4^2 + 6^2 = c^2
c^2= 52
c= sqrt of 52
Then the perimiter of the triangle is: (4+6+sqrt of 52)
Now you find the L.A.
(4+6+sqrt of 52) (8)
(10 + 2 sqrt of 13) (8)
80 + 16 sqrt 13
