Question

area of a rombis is 90 cm². if the length of one diagonal is 10 cm , find the length of the other diagonal​

Answer 1

Given:-

• Area of rhombus $\longrightarrow$ 90cm²
• Length of one diagonal $\longrightarrow$ 10cm

To Find:-

• Length of other diagonal $\longrightarrow$?

Solution:-

$\bf\implies Area \longrightarrow \frac{pq}{2}$

$\bf\implies 90 \longrightarrow \frac{10q}{2}$

$\bf\implies q \longrightarrow \frac {90×2}{10}$

$\bf\implies q \longrightarrow 18cm$

The length of second diagonal is 18cm
