For example: What is the area of the trapezoid?
Solution:
In the above trapezoid:
Parallel bases are 12 cm and 20 cm.
Height of the trapezoid is 5 cm.
Area of the trapezoid = ½ * (base1 + base2) × height
= ½ * (12+20) * 5
= ½ * (32) * 5
= 80
Therefore, the area of the trapezoid is 80 square centimeters.
