Look at the parallelogram in the figure below.
Express its area in terms of a.
To find the area of the given parallelogram, we apply the formula for the area of a parallelogram, which is:
Here, the base is given as cm and the height is given as .
Plugging these values into the formula, we have:
Simplifying this, we get:
Therefore, the area of the parallelogram, expressed in terms of , is cm².
The correct choice from the given options is therefore choice 3: cm².
cm²
A parallelogram has a length equal to 6 cm and a height equal to 4.5 cm.
Calculate the area of the parallelogram.
The question asks for the area in terms of a, meaning your final answer should still contain the variable. You're finding an expression, not a specific number!
In a parallelogram, the height is always perpendicular to the base. Look for the right angle symbol (small square) in the diagram - that shows the height measurement.
Remember: use the base and height, not just any two sides! The height is the perpendicular distance between parallel sides, shown by the vertical line in the diagram.
No, is already in its simplest form. Since 52 and the variable a have no common factors to cancel, this is your final answer.
Always include units in your final answer! Since both measurements were in cm, the area is in cm². The variable a represents a number, so the full answer is 52a cm².
