The Solution.

The lateral area of the given pyramid is the total area of the 5 triangular faces of the pyramid.

So, we have

$\text{Lateral Area of the pyramid = 5(}(1)/(2)bh)$

In this case,

$b=5\text{ ft, h=13 ft}$

Substituting these values in the formula above, we get

$\text{Lateral Area of the pyramid = 5}*(1)/(2)*5*13$
$\text{Lateral Area of the pyramid = }(25*13)/(2)=(325)/(2)=162.5ft^2$

Hence, the correct answer is 162.5 square feet (option 4).
