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.
Best Answer: Wounds start healing before scabs form. In fact, scabs are not necessary for a wound to heal. Studies have shown that wounds kept covered heal up to 3 days faster than wounds left uncovered; covered wounds stay moist and often don't scab at all. So, I would advise you use some antibacterial ointment such as neosporin and then bandage your cut.
