To find the area of the quadrilateral, we first need to calculate the semi-perimeter:
Semi-perimeter = (6 + 6 + 10) / 2 = 22 / 2 = 11 cm
Next, we can use Heron's formula to calculate the area:
Area = √[11(11 - 6)(11 - 6)(11 - 10)]
Area = √[11(5)(5)(1)]
Area = √[11(125)]
Area = √1375
Area ≈ 37.08 cm²
Therefore, the area of the quadrilateral is approximately 37.08 cm².
