The answer to your question is At = 48 + 36 $\sqrt{3}$

Step-by-step explanation:

Area = Area of the base + Lateral area

a) Area of the base

Area = length x height / 2

length = 12

height² = 12² - 6²

= 144 - 36

= 108

height = $\sqrt{108}$ = 6 $\sqrt{3}$

Area = 12 x 6 $\sqrt{3} / 2$

= 36 $\sqrt{3}$

b) Lateral area

height² = 10² - 6²

= 100 - 36

= 64

height = 8

Area = 12 x 8/2

= 48

c) Total area

At = 48 + 36 $\sqrt{3}$
