Question
Answer:
Answer:750 cm^2Step-by-step explanation:Assuming this is an area problem,To find the area of the whole shape, first we must find the area of each part. We will start from the top and work our way down.Area is very simple for squares, it is just base times height. The complex part is when it's in weird shapes like this.First, find the area of the top square (the squares are sectioned off by dotted lines.)14*9=126, so that part equals 126 cm^2 (the ^ symbol means to square the following number.)The left box can go off of the height of the right box for that middle segment.Both of those 'wings' are the same equation, 13*9, since the dotted lines can help us establish symmetry.13*9 = 117, so both of those wings are 117 cm^2the middle box is 14*13, since those are the measurements corresponding with it from other parts of the box.14*13 = 182The box below that is 14*914*9 = 126the bottom box is 14*13, which is 182 as well.14*13 = 182.Finally, add all of our boxes sizes together. 126+117+182+117+126+182=750.So, the total amount of wrapping paper used is 750 cm^2.I am willing to elaborate if needed, and added a diagram for help understanding!
