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.
Tips: 1  If the wound is open and you can see the intestines, find a moist, sterile dressing to place on top of the wound (to protect the organs). 2  If the intestines are ripped open, the victim needs immediate medical care. 3  The victim should take nothing at all by mouth until the pain lets up, and then wait a day or two.
