Question

Find the area of rhombus whose diagonals are of length 20 cm and 15 cm.
​

Answer 1

☆ Solution ☆

Given :-

• Diagonals of the rhombus are 20 cm and 15 cm.

To Find :-

• The area of the rhombus.

Step-by-Step-Explaination :-

As we know that :-

Area of the rhombus = 1/2 × D1 × D2

Where,

• D1 = 20 cm

• D2 = 15 cm

Putting the respective value,

Area of the rhombus = 1/2 × 20 × 15

Area of the rhombus = 300/2

Area of the rhombus = 150

Hence,

Area of the rhombus = 150 cm

Know More :-

Perimeter of Rectangle = 2( L + B )

Perimeter of square = 4 × Side

Perimeter of triangle = AB + BC + CA

Area of Rectangle = L × B

Area of Square = ( side ) ²

Area of Rhombus = Product of Diagonal/2.

Area of Parallelogram = Base × Height.

Area of triangle = 1/2 × base × height .

Answer 2

Given :-

• Length of First Diagonal = 20cm
• Length of Second Diagonal = 15cm

To Find :-

• The Area of the Rhombus .

Solution :-

⇒ Area = ½ × product of its diagonals

⇒ Area = ½ × ( 20 × 15 )

⇒ Area = ½ × 300

⇒ Area = 150cm²

________________

Therefore, The Area of Rhombus is 150cm²
