Question

Each side of a rhombus is 3x that is perimeter is 120cm, then its side is-

Answer 1

Answer:

3x+ 3x +3x+ 3x= 120cm

12x = 120

x= 120/ 12 =10

3x =3 ×10= 30

Answer 2

Answer:

Hence, value of side of rhombus will be 30 cm

Step-by-step explanation:

In context to question asked,

We have to determine the value of side of rhombus.

As per data given,

We have,

Side of rhombus =  3x cm

Perimeter of rhombus = 120 cm

As we know that,

• Rhombus is a special type of quadrilateral whose all the sides are equal and parallel but none of the angle are of right angle.

• Perimeter can be calculated by adding the length of all the outer sides of the figure.

So, perimeter of rhombus can be determined by using formula,

$Perimeter = side + side + side + side = 4 \times side$

So, for determining the value of perimeter,

We will put the value of side of rhombus in above formula

Thus we will get the value of side of rhombus as,

$Perimeter = 4\times side\\=>120 = 4 \times 3x\\=>12x = 120\\=>x = \frac{120}{12} = 10\:cm\\Side = 3x = (3\times 10)= 30\:cm$
