The lateral surface area of a frustum of a pyramid is given by the formula:

A = (h * (a + b)) / 2

Where:
A = lateral surface area
h = height of the frustum
a = length of the upper side
b = length of the larger side

In this case, h = 4 cm, a = 9 cm, and b = 15 cm. Plugging these values into the formula, we get:

A = (4 * (9 + 15)) / 2
A = (4 * 24) / 2
A = 96 / 2
A = 48 cm²

Therefore, the lateral surface area of the frustum is 48 cm².
