Question

A house shaped like an octagon has a large porch, what is the area of the house and porch

Answer 1

Area of the house and porch is 875 square feet.

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 =
`2[(1)/(2)* 5* 5]`

= 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.
