Answer :
Answer:
Area of the house and porch is 875 square feet.
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 = [tex]2[\frac{1}{2}\times 5\times 5][/tex]
= 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.
