Answer 2

Question:

• The area of rhombus is 190cm² and one of its diagonal is 20cm. Find the other diagonal.

___________

Explanation:-

Given :-

• Area of rhombus = 190cm²
• One diagonal = 20cm

To finD:

• Other diagonal

Solution:-

We are given that area of rhombus is 190cm² and one diagonal is 20cm

We know that :-

$\large{\sf{Area_{(rhombus)}=\:\dfrac{d_{1} \times d_{2}}{2}}}$

Where,

• $\small{\tt{d_{1}} \:=\: first \:diagonal}$ ••••20cm given
• $\small{\tt{d_{2}} \:=\: second\:diagonal}$ •••• have to find.

Putting values in formula :-

$\large{\sf{Area_{(rhombus)}=\:\dfrac{d_{1} \times d_{2}}{2}}}$

→ $\large{\sf{190=\:\dfrac{20\times d_{2}}{2}}}$

→ $\large{\sf{ 190\:=\: 10 × d_{2}}}$

→ $\large{\sf{ d_{2} \:=\: \dfrac{190}{10}}}$

→ $\large{\sf{d_{2} \:=\: 19}}$

→ $\huge{\boxed{\large{\green{\mathfrak{another\: diagonal \: of\: rhombus\:=\: 19cm}}}}}$
