In the quadrilateral ABCD, side AB is 15 cm less than BC, and side AD is 30 cm larger than CD. What is the perimeter of this quadrilateral if AB = CD = 16 cm?
AB = CD = 16 cm;
AB is less than BC by – 15 cm;
АD is more than СD by – 30 cm;
Find the perimeter of the quadrilateral.
To do this, we must find the side BC and AD, then find the perimeter.
BC = 16 + 15 = 31 cm;
AD = 16 + 30 = 46 cm;
16 + 16 + 31 + 46 = 109 cm
Answer: The perimeter of the quadrangle is 109 cm.
