Question

The lengths of two diagonals of a rhombus are 12cm and 7cm. Find the area of a rhombus​

Answer 1

$\huge\fbox\textit{\blue{Aɴsᴡᴇʀ}}$

length of one diagonal (d1) = 12 cm

length of another diagonal (d2) = 7 cm

area of Rhombus = 1/2 × d1 × d2

= 1/2 × 12 × 7

= 42 cm²

Answer 2

Answer :-

Area of rhombus = 42 sq. cm.

Explanation :-

Given :

• Length of two diagonals of a rhombus are 12 cm and 7 cm.

To Find :

• Area of rhombus.

Solution :

We know that,

❖ Area of rhombus = (d₁ × d₂)/2.

➠ Area of rhombus = (12 × 7)/2.

➠ Area of rhombus = 84/2.

➠ Area of rhombus = 42 sq. cm.

Therefore, Area of rhombus = 42 sq. cm.

Extra Information :-

• Area of Rectangle = l × b.

• Area of Square = side × side.

• Area of rhombus = (d₁ × d₂)/2.

• Area of Triangle = 1/2 × base × height.
