Question

Q.1. The area of rhombus is 840 cm². And one of the diagonals is 12 cm find the other
diagonal.​

Answer 1

Answer:

Here's your answer -

Given - Area of Rhombus - 84cm²

One of its diagonal = 12 cm

To find - The other diagonal of the Rhombus

Calculation -

Area = 1/2 × (Product of diagonals)

That is,

Area = 1/2 × d1 × d2

here, d1 = 12cm

Let the other diagonal be x

84 = 1/2 × 12 × x

84 = 6x

x = 84/6

=> 14 cm

Therefore the measure of other diagonal is

14 cm

Hope it helps!

Answer 2

Answer:

70cm

Step-by-step explanation:

area of rhombus = 840 cm²

diagonal. =12 cm

area= dia×dia

other diagonal=

$\frac{840}{12} = \frac{70}{1}$

other diagonal= 70cm
