[ProQuest Ebook Central - (tlu.ee)](https://ebookcentral-proquest-com.ezproxy.tlu.ee/lib/tallinn-ebooks/reader.action?docID=5987181&ppg=1) **Task definition** There are two doors infront of the house. Measure the door on the left side (pointing to pirita) include the door edges in your measurement. Then calculate the door area. Then find out the doors diagonal or measure it. Then round the answer to a whole number. Then subtract 175 from that number. That will be your paragraph number. Use the paragraph number and subtract 62 from the number to find your answers. **Solution move** 1. Calculate the door area. 2. Find out the door diagonal. 3. Round it to a whole number. **Mathematical calculation step** 2×(216+170)= 772 d = √(216² + 170²)=√75 556 274, 874 274, 874≈ 275 275-175= 100 100-62= 38 38+62=100 Hint 1 The formula for the door area: P= (a+b) S= ab Hint 2 Then use the formula d = √(l² + w²) to find out the doors diagonal or measure it.
