Question

Q.1) Find the area of rhombus if the diagonal (d1) = 17cm and diagonal (d2) =
12cm.​

Answer 1

Answer:

Area of the Rhombus = 102 cm²

Step-by-step explanation:

Given :

First diagonal = 17 cm

Second diagonal = 12 cm

To find :

The area of the Rhombus

Taken :

To find the area of the Rhombus use this formula -:

$\boxed{\sf{A=\dfrac{1}{2}\times d_{1}\times d_{2}}}$

Where,

A = Area of the Rhombus

$\sf{d_{1}}$ = First diagonal

$\sf{d_{2}}$ = Second diagonal

Solution :

$\leadsto\sf{A=\dfrac{1}{2}\times17\times12}$

$\leadsto\sf{A=\dfrac{1}{\cancel{2}}\times\cancel{204}}$

$\leadsto\sf{A={102cm}^{2}}$

So , the area of the Rhombus is 102 cm² .

Extra information :

▪︎To find the perimeter of the Rhombus -:

$\boxed{\sf{P=4a}}$

Where,

P = Perimeter

a = Side

▪︎To find the diagonal of the Rhombus -:

$\boxed{\sf{d_{2}=2\dfrac{A}{d_{1}}}}$
