Theory. Perimeter of a trapezoid

Trapezoid (Trapezium) - is quadrilateral with at least one pair of parallel sides.

The perimeter of a trapezoid is equal to the sum of the lengths of its sides.

P = a + b + c + d

where P - perimeter of a trapezoid,
a, с - the length of 2 trapezoid bases,
b, d - length of the legs.
