Step-by-step explanation:

Given question is incomplete: find the complete question in the attachment.

From the figure attached,

Area of the octagonal house and porch = Area of the rectangle - Area of two rectangles cut off from the top corners of the rectangle

Area of the rectangle = 30×30 = 900 square feet

Area of the triangles =

                                  = 25 square feet

Area of the house and porch = 900 - 25

                                                = 875 square feet

Therefore, area of the house and porch is 875 square feet.
