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.
Dressing size should be based on and appropriate to the size of the wound. For wound covers, the medically necessary pad size should usually be about 2 inches greater than the dimensions of the wound. For example, a 5 cm X 5 cm (2 in. X 2 in.) wound would require a 4 in.
