Calculate the Area of a Rhombus with Diagonals 4 and 7 Units

Question

Given the rhombus in the drawing:

What is the area?

00:00 Find the area of the rhombus

00:03 We will use the formula to calculate the area of a rhombus

00:08 (diagonal multiplied by diagonal) divided by 2

00:14 We will substitute appropriate values and solve to find the area

00:25 And this is the solution to the problem

Let's remember that there are two ways to calculate the area of a rhombus:

The first is the side times the height of the side.

The second is diagonal times diagonal divided by 2.

Since we are given both diagonals, we calculate it the second way:

$\frac{7\times4}{2}=\frac{28}{2}=14$
