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 were assigned to keep their stitched wounds dry and covered for at least 48 hours (the control group), and others were told to keep the dressing on to absorb immediate bleeding, then remove it and bathe as normal in the first 12 hours. None of the patients were on antibiotics.
