1. Consider a right-angled triangle, in which the lateral side of the trapezium is hypotenuse, the height of the legs and part of the lower base (10 – 2) / 2 = 4 centimeters of the second leg.
2. Let’s define the side.
√ (4² + 3²) = √25 = 5 centimeters.
3. Find out the size of the area.
(2 + 10) / 2 * 3 = 18 cm².
4. What is the perimeter?
10 + 2 + 5 * 2 = 22 centimeters.
Answer: The area is 18 square centimeters. The perimeter is 22 centimeters.
