The answer is 35cm 2. To find the area, you need to divide the shape into a rectangle and a triangle: The area of the rectangle is 5 Ã 4 = 20cm 2. The base of the triangle is calculated by subtracting the base of the rectangle (4cm) from the total length of the shape (10cm).
A handful of studies have found that when wounds are kept moist and covered, blood vessels regenerate faster and the number of cells that cause inflammation drop more rapidly than they do in wounds allowed to air out. It is best to keep a wound moist and covered for at least five days.
Because this is a type of puncture wound, the skin opening is not sutured closed. This is to reduce problems in the event of an infection. As a result, blood may ooze from the wound opening during the first 24 hours. While at home: Keep the wound clean and dry. If a bandage was applied and it becomes wet or dirty, replace it. Otherwise, leave it in place for the first 24 hours. Clean the wound daily: After removing the bandage, wash the area with soap and water.
