To find the area of a irregular shape with sides measuring 21ft, 18ft, 12ft, and 38ft, you can use Heron's formula. First, calculate the semi-perimeter by adding all the sides together and dividing by 2: (21 + 18 + 12 + 38) / 2 = 44.5ft. Then, apply Heron's formula: Area = √[44.5(44.5-21)(44.5-18)(44.5-12)(44.5-38)]. After performing the calculations, the area of the shape is approximately 216.15 square feet.

It is not possible to answer the question.

The fact that there are four lengths given suggests that the shape is quadrilateral. However, for a quadrilateral, the side lengths do not provide enough information since a quadrilateral can be skewed: from a trapezium to a narrow needle-like shape.
