Question

The area of rhombus is $98c{m}^2$. If one of its diagonals is 14 cm, the length of the other diagonal is ___ cm.

• A. 224
• B. 12
• C. 14
• D. 16

Answer 1

The correct option is C

14

Area of Rhombus $=\frac{1}{2}\times$ Product of diagonals

$98=\frac{1}{2}\times d_1\times d_2$

$\text{/}{98}^{14}=\frac{1}{\text{/}2}\times \text{/}{14}^{\text{/}7}\times d_2$

$d_2=14cm$

Hence (c)
