Question

Area of a rhombus is 90cm . If the length of one diagonal is 10cm the length of other diagonal is

Answer 1

Answer:

Step-by-step explanation:

Area of rhombus = product of diagonals/2

Let the unknown diagonal be d2

So we can write

90 = (10 × d2)/2

10d2 = 180

d2 = 180/10

= 18 cm

So the other diagonal is 18 cm
