Calculate Parallelogram Area: Using 7cm Base and 4cm External Height

Question

ABCD is a parallelogram.

BE is its external height.

DC = 7 cm
BE = 4 cm

Calculate the area of the parallelogram.

00:11 Let's find the area of the parallelogram.

00:15 We use the formula: area equals height times base length. Are you ready?

00:27 Next, we plug in the values for the height and the length of the base.

00:31 Now, let’s calculate these numbers to find the solution.

00:40 And there you have it! That's how we solve this question.

To solve this problem, we'll use the formula for the area of a parallelogram:

$\text{Area} = \text{Base} \times \text{Height}$

Here, the base $DC$ is given as 7 cm, and the height $BE$ is given as 4 cm.

Now, substituting the known values into the formula, we get:

$\text{Area} = 7 \, \text{cm} \times 4 \, \text{cm} = 28 \, \text{cm}^2$

Thus, the area of the parallelogram is $\boxed{28 \, \text{cm}^2}$ .

28 cm²
