| March 8, 2021 | education
To solve this problem, remember that the perimeter is equal to the sum of all sides.
Knowing the size of the bases of the trapezoid and the total perimeter of the trapezoid, we can find the length of the side.
First, let’s find the sum of the sides:
83 – 19 – 28 = 36 (cm).
Since the sides of an isosceles trapezoid are equal, the side is equal to:
36/2 = 18 (cm).
Answer: 18 cm.
