The width of a child's hand can vary depending on their age and size, but on average, it ranges from about 3 to 4 inches (7.5 to 10 cm) for younger children. As they grow, their hand size will increase, with older children typically having hands that measure closer to 4 to 5 inches (10 to 13 cm) in width. Measuring a child's hand can provide a useful reference for fitting gloves or assessing growth and development.
Area = Length*Width so Width = Area/Length. Therefore the Width can be calculated. Then, perimeter = 2*(Length + Width) and everything on the right hand side of the equation is known so the perimeter can be calculated.
