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.
Some wounds that have been open for more than six hours also should not be closed with sutures. In these cases, the wound may be cleaned, kept open under a bandage and allowed to heal slowly from the outer edges inward. Your doctor will check whether your sense of touch is normal around the cut.
