Question

The area of a rhombus is 360 cm square and 1 diagonal is 30 cm. Find the other diagonal.​

Answer 1

Answer:

Step-by-step explanation:

area of rhombus = 1/2 × de × de

=> 1/2 × 40 × d2 = 360

=> 20d2 = 360

=>d2 = 360/20

=> d2 = 18 cm

Answer 2

Answer:

other diagonal = 24 cm

Step-by-step explanation:

area of rhombus =

$\frac{1}{2} \times diagonal \: 1 \times diagonal \: 2$

let's take measure of the unknown diagonal be x

=》

$360 = \frac{1}{2} \times 30 \times x$

=》

$360 = 15 \times x$

=》

$\frac{360}{15} = x$

=》

$24$

so, the length of the other diagonal is 24 cm
