Answer:
Lateral area of the pyramid = 72 unit²
Step-by-step explanation:
Lateral surface means side part of pyramid. So we nee need to find area of 6 triangles with base 4 and height 6.
Lateral area of the pyramid = 6 x Area of 6 triangles with base 4 and height 6
[tex]\texttt{Lateral area of the pyramid = }6\times \frac{1}{2}\times 4\times 6\\\\\texttt{Lateral area of the pyramid = }72unit^2[/tex]
