| Find the perimeter of a quadrilateral ABCD with sides equal to A B is equal to BC equal to 15 cm CD is equal to 20mm, DA = 25mm.
The perimeter of a quadrilateral ABCD is found as the sum of the lengths of its four sides:
PABCD = AB + BC + CD + AD;
AB = BC = 15 cm;
CD = 20mm = 2cm (since 1cm = 10mm);
AD = 25mm = 2.5cm (since 1cm = 10mm);
PABCD = 15cm + 15cm + 2cm + 2.5cm = 34.5cm.
Answer: PABCD = 34.5 cm.
