Step-by-step explanation:
First, to figure out the actual dimensions for Part A, you need to turn the inches into feet. If the window is 5 inches long and 1 inch is 1.5 feet, you multiply 1.5 and 5 to get 7.5 feet long. Same goes for the length. which will be 1.5×4 which equals 6 ft wide.
For part B, the perimeter is equal to all the side lengths added. The equation would be 6+6+7.5+7.5 which equals 27 ft. Area is equal to the length times the width. The equation would be 6×7.5 which comes out to 45 ft!
