1. 48 square feet

2. 308 square feet

Step-by-step explanation:

1.

The entry terrace is shaped as a trapezoid and the area of a trapezoid is given as:

Area of Trapezoid =

Where

b_1 and b_2 are the 2 parallel bases

and h is the perpendicular height

From the diagram, we see that the 2 bases are 16 and 8 and height is 4.

Plugging into the formula, we get:

Area of Entry Terrace =

2.

The total area comprises of the area of entry terrace + playroom + back porch.

The area of the back porch is 6 * 6 = 36 (it is shaped like a square and square has area of side * side)

The area of the playroom is 14 * 16 = 224 (it is a rectangle and rectangle has area of base * height)

Total area of treehouse = 48 + 36 + 224 = 308 square feet
