If a rhombus has diagonals of length 20 inches and 48 inches, what is the length of its perimeter? show the work you used to find your answer.

Perimeter of Rhombus = 104 inches  

Step-by-step explanation:

To find the Perimeter of Rhombus we use the formula

Perimeter of rhombus = 4*Length

We need to find the length of rhombus.

if the rhombus has diagonals, it makes four right angled triangles (as shown in figure).

Since 4 triangles are made so, each side of triangle is half of the length of the diagonal.

In our case: Length of diagonals are: 20 and 48

but the Length of sides of triangle will be: 10 and 24

To find the side of rhombus, we can use Pythgoras theorem since the triangles are right angled.

c² = a²+b²

c² = (10)² + (24)²

c² = 100 + 576

c² = 676

√c²= √676

c = 26

So, the length of side of rhombus is 26 inches

Perimeter = 4*length

                = 4*26

                = 104 inches

Perimeter of Rhombus = 104 inches.
