Answer:
x = 6 cm
Step-by-step explanation:
• in the parallelogram, if we consider the side of length 12
as the base then the corresponding height is 5.
In this case the area of our parallelogram = 5 × 12 = 60 cm²
………………………………………………
• in the parallelogram, if we consider the side of length 10
as the base then the corresponding height is x.
In this case the area of our parallelogram = 10 × x = 10x cm²
………………………………………………
In order to determine x ,we equate the two different results
that we got for the same area .
In other words ,we have to solve the equation 10x = 60.
10x = 60
⇔ x = 60/10 = 6
