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.
In order to form the new skin and heal the wound, your skin has to produce new skin cells. These cells are growing sooner in a moist environment. You can create this condition by covering your wounded area with moist wound bandage. However, you also need to keep the wound moist, not wet, to avoid possible infection.
