Calculate Parallelogram Area: Using 3cm Base and 6cm External Height

Question

ABCD is a parallelogram.

BE is its external height.

AD = 3 cm
BE = 6 cm

Calculate the area of the parallelogram.

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

00:15 We'll use the formula. Area equals height times the length of the side. Ready?

00:25 First, identify the side that is the height of the parallelogram.

00:31 Substitute the given values into the formula, calculate, and solve.

00:37 And that's how we find the solution!

To solve this problem, we proceed with the following steps:

Step 1: Identify the base of the parallelogram as $AD = 3 \, \text{cm}$ .
Step 2: Identify the external height as $BE = 6 \, \text{cm}$ .
Step 3: Use the area formula for the parallelogram: $\text{Area} = \text{Base} \times \text{Height}$
Step 4: Substitute the given measurements into the formula: $\text{Area} = 3 \, \text{cm} \times 6 \, \text{cm}$
Step 5: Compute the area: $\text{Area} = 18 \, \text{cm}^2$

Therefore, the area of the parallelogram is $18 \, \text{cm}^2$ , which matches the given answer choice.

The correct answer is choice 2: 18 cm².

18 cm²
