In geometry, a quadrilateral can be defined as a two-dimensional, closed shape which has four straight sides. Heron's Formula depends on knowing the semiperimeter, or half the perimeter, of a triangle. For our MAH, the three sides measure: MA = 7 cm; AH = 13.747 cm; HM = 14 cm A quadrilateral is a 2-dimensional, closed, and four-sided polygon with four angles. The following formulas give the area of a general quadrilateral (see Figure 1, left, for the notation)..
