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.
Protect your wound. Your wound can swell, bleed, or split open if it is stretched or bumped. You may need to wear a bandage that supports your wound until it is completely healed. Minimize your scar. Use sunblock if your wound is exposed to the sun. Apply it every day after the stitches are removed.
