Question

Find the area of a rhombus whose diagonals are 4.8cm and 1.4cm.​

Answer 1

We know,

Area of rhombus = $\frac{1}{2}$ × d1 x d2

area =  $\frac{1}{2}$ × 4.8 x 1.4

area = 2.8 $cm^{2}$

Answer 2

Answer :-

• The area of rhombus is 3.36cm².

Step-by-step explanation :

To Find :-

• The area of rhombus

Solution :-

Given that,

• The two diagonals of rhombus are 4.8cm and 1.4cm

As we know that,

Area of rhombus = 1/2 × d₁ × d₂,

Where,

• d₁ = shorter length of diagonal
• d₂ = longer length of diagonal

Here,

• d₁ = 1.4cm
• d₂ = 4.8cm.

According the question,

=> Area = 1/2 × d₁ × d₂

=> 1/2 × 1.4 × 4.8

Dividing 2 and 4.8 with 2

=> 1 × 1.4 × 2.4

=> 1.4 × 2.4

=> Area = 3.36

• The area of rhombus is 3.36cm².

Perimeter of rhombus :-

• Perimeter = 4 × side

Area of rhombus :-

We can find out the area of rhombus is three ways,

By using diagonals

• Area = 1/2 × d₁ × d₂

By using base and height

Area = base × height

• By using trinogeometry

Area = b² × sin(a)
