Calculate the perimeter of the quadrilateral if the length of one side is 16 cm, the other side is 4 cm longer
Calculate the perimeter of the quadrilateral if the length of one side is 16 cm, the other side is 4 cm longer, and the sum of the lengths of the two remaining sides is 45 cm.
The perimeter of a quadrilateral is equal to the sum of its four sides. From the condition of the problem, the length of one side of the quadrangle is known, the sum of the lengths of the two sides of the quadrilateral. To answer the question of the problem, you need to find the length of the fourth side of the quadrangle.
1) Calculate the length of the side of the quadrangle.
16 + 4 = 20 centimeters.
Let’s answer the question of the problem.
2) Find what the perimeter of the quadrangle is.
16 + 20 + 45 = 81 centimeters.
Answer: The perimeter of the quadrangle is 81 centimeters.
