The area of parallelogram ABCD is 72Y cm².
Calculate DC.
To find the side length of parallelogram with an area of :
Therefore, the length of is .
Calculate the area of the parallelogram based on the data in the figure:
The base can be any side of the parallelogram, but the height must be the perpendicular distance between parallel sides. Look for the dashed line marked with 9 - that's your height!
The area is given as , which contains the variable y. When you divide , the variable stays in your answer.
Yes! You could use side AD as the base, but then you'd need the perpendicular height to that side. The calculation Area = base × height always works regardless of which side you choose as base.
The variable y represents an unknown value with units of length (cm). It could be any positive number - the relationship between area and sides stays the same regardless of y's actual value.
Multiply your answer by the height: . This matches the given area, so 8y cm is correct!
