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.
Exposing the wound to the air will induce scabs formation. These scabs will definitely limit your movement because your wound will be extremely dry and hardened. On the contrary, when you keep the wound covered and moist, it will have very little number of scab and thus, will give you more room for mobility. Keeping your wound clean, covered, and moist might be the best way to speed up the healing process, as it provides suitable environment for the new cells to grow. Scarring can also be minimized, which is a very good news for everyone.
