Question

area of a rhombus is 90 cm² if the length of one diagonal is 10 centimetre then find the length of other diagonal​

Answer 1

Answer:

it so easy area of rhombus=1÷2×d1×d2

1÷2×10×x=90

5×x=90

x=90÷5

x=18

Answer 2

Answer:

18 cm

Step-by-step explanation:

since,

area of rhombus, A = pq/2

where p & q are the diagonals.

so, 90 = 10q/2

90 = 5q

q = 18 cm
