Adwin purchased a new door for the front of his house as shown below. He would like to stain the door using a cherry wood stain. To determine how much stain to buy, Adwin first needs to find the area of the door. How many square feet is the door? Use 3.14 for. The door consist of a rectangle measuring 4 ft by 7 ft and a semicircle with a diameter of 4 feet. Find the area of the rectangle… Find the area of the semicircle… ½ since it is a semicircle 3.14 for pi The radius is half the diameter.

Adwin also purchased weather stripping to go around the door. How many feet of weather stripping did he buy? The door consist of a rectangle measuring 4 ft by 7 ft and a semicircle with a diameter of 4 feet. Weather stripping would be the perimeter of door… (3 sides of the rectangle and ½ the circumference of the circle. ½ since it is a semicircle 3.14 for pi diameter
