We have a pyramid with a base with an equilateral triangle.

To find the area of this triangle, we use the next formula:


A_t=(Base\ast Height)/(2)

Looking at the given image, we can find that:

Base = 8cm

Height = 7 cm

Therefore, we can replace these values on the given equation:


\begin{gathered} A_t=(\left(8cm\right?\ast\left(7cm\right?)/(2) \\ A_t=(56cm^2)/(2) \\ A_t=28cm^2 \end{gathered}

The correct answer is the last option.
