trapezoid is form by the following points:

A (-9, 3), B (3, 7), C (12, -4), D (-12, -12)

Find the perimeter and the area of the trapezoid formed by these points. Round the answers to 3 digits after the decimal point. Specify the unit/s of measurements. Display the final answer in the text-box (perimeter = , area =). For sign use ==, for "2" use "units sq.

Use the formula for the area of the trapezoid:

Area = 1/2height (base1+base2)
