Calculate the perimeter of a quadrilateral if the length of one side is 16cm, the other side is 4 longer, and the sum of the lengths of the two remaining sides is 45cm.
The perimeter of a quadrilateral is the sum of the lengths of all its sides.
The length of the first side is 16 centimeters.
The length of the second side is 4 more, that is, 16 + 4 = 20 centimeters.
The sum of the lengths of the third and fourth sides is 45 centimeters.
Find the perimeter of the quadrangle:
P = 16 + 20 + 45 = 81 centimeters.
Answer: The perimeter of the quadrangle is 81 centimeters.
