Examples with solutions for Area of a Parallelogram: Verifying whether or not the formula is applicable

Exercise #1

A parallelogram has a length equal to 6 cm and a height equal to 4.5 cm.

Calculate the area of the parallelogram.

6664.54.54.5

Video Solution

Step-by-Step Solution

To solve this problem, let's apply the formula for the area of a parallelogram:

The formula for the area of a parallelogram is Area=base×height \text{Area} = \text{base} \times \text{height} .

Here, the base of the parallelogram is 6 cm, and the height is 4.5 cm.

Substituting these values into the formula gives:

Area=6×4.5 \text{Area} = 6 \times 4.5

Performing the multiplication:

Area=27 \text{Area} = 27 square centimeters.

Therefore, the area of the parallelogram is 27cm2 27 \, \text{cm}^2 .

Referring to the given multiple-choice answers, the correct choice is:

Choice 3: 27 27 .

Answer

27

Exercise #2

Calculate the area of the parallelogram based on the data in the figure:

101010444

Video Solution

Step-by-Step Solution

In this particular problem, despite being given certain measurements, the diagram lacks sufficient clarity to identify which corresponds definitively as the base and which as the perpendicular height of the parallelogram. This insufficiency means that without further context or labeling to avoid assumptions that may lead to error, it is not feasible to calculate the area confidently using the standard formula.

Thus, the answer to the problem is that it is not possible to calculate the area with the provided data.

Answer

It is not possible to calculate.

888555

Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the base and height from the information provided.
  • Step 2: Apply the formula for the area of a parallelogram.
  • Step 3: Calculate the area by multiplying the base and height.

Now, let's work through each step:
Step 1: The base of the parallelogram is given as 88 units, and the height is given as 55 units.
Step 2: We use the formula for the area of a parallelogram: Area=base×height \text{Area} = \text{base} \times \text{height} .
Step 3: Plugging in the given values, we calculate the area as follows:
Area=8×5=40 \text{Area} = 8 \times 5 = 40 .

Therefore, the area of the parallelogram is 40 40 square units, which corresponds to choice 2.

40

Exercise #5

Calculate the area of the parallelogram using the data in the figure:

999444

Video Solution

Step-by-Step Solution

To solve this problem, we must calculate the area of the given parallelogram using the formula:

Area=base×height \text{Area} = \text{base} \times \text{height}

Assuming the figure (as described) provides a base of 9 9 units and a height of 4 4 units, we substitute these values into the formula:

Area=9×4=36 square units \text{Area} = 9 \times 4 = 36 \text{ square units}

The necessary calculations have been carried out using the correct dimensions, ensuring dimensional consistency and precise arithmetical methods. Therefore, the calculated area of the parallelogram is 36 36 .

Given the multiple-choice options, the correct choice is the one specifying the area as 36 36 , confirming the answer provided in choice 3.

Answer

36

Exercise #6

Calculate the area of the parallelogram using the data in the figure:

555888333

Video Solution

Step-by-Step Solution

From the given constraints, it is impossible to confidently compute the area of the parallelogram because of insufficient and unclear relationships between provided figures and the calculations they must produce. Clarity on which numbers correspond to the height and base—as or any definitional angles—is absent.

The correct answer, aligning with acknowledged drawing limitations, is: It is not possible to calculate.

Answer

It is not possible to calculate.
