Step-by-step explanation:
<u>Area formula for equilateral triangle with side a:</u>
<u>The base area is:</u>
The three lateral surfaces have same sides of 10, 10 and 12.
<u>Find each surface area using heron's formula:</u>
- s = P/2 = (10 + 10 + 12)/2 = 16
- s - a = 16 - 10 = 6
- s - b = 6
- s - c = 16 - 12 = 4
![A = \sqrt{s(s-a)(s-b)(s-c)} =\sqrt{16*6*6*4} =48](https://tex.z-dn.net/?f=A%20%3D%20%5Csqrt%7Bs%28s-a%29%28s-b%29%28s-c%29%7D%20%3D%5Csqrt%7B16%2A6%2A6%2A4%7D%20%3D48)
<u>Total surface area is:</u>
