Question

The area of rhombus is 120cm^2 and one of the diagonal is 8 cm. Find the another diagonal​

Answer 1

Step-by-step explanation:

area formula is -- 1/2×d1×d2

d is the digonal

hope this is helpful to you!!!

Answer 2

Given :

• Area of rhombus = 120 cm²
• Length of diagonal = 8 cm

To find :

• Length of another diagonal

According to the question,

$\sf{ : \implies Area \: of \: rhombus = \dfrac{1}{2} \times d _{1} \times d_{2} }$

$\sf : \implies{ {120 \: cm}^{2} = \dfrac{1}{2} \times 8 \: cm \times x}$

$\sf : \implies{ {120 \: cm}^{2} \times 2 = 8 \: cm \times x }$

$\sf : \implies{ {240 \: cm}^{2} = 8 \: cm \times x}$

$\sf : \implies{ \dfrac{240}{8} \: cm = x}$

${ \underline{ \boxed{ \sf \pink{ : \implies{ \bm3 \bm0 \: c m =x}}}}}$

${ \therefore{ \underline{\sf{So \:,the \: length \: of \: other \: diagonal \: is \: 3 0 \: cm}}}}$
