Example 1: Find the area of a parallelogram with a base of 12 centimeters and a height of 5 centimeters. Example 2: Find the area of a parallelogram with a base of 7 inches and a height of 10 inches.

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. Area = b ∙ h ÷ 2
