Question

The area of rhombus is 40 cm² and one of the
diagnols is 16cm. find out diagnol.​

Answer 1

Answer:

Step-by-step explanation:

Perimeter = 40 cm

Side = 40 / 4 = 10 cm

D1 = 16 cm

D2 = 2 × sqrt [side^2 - (d1/2)^2]

= 2 × sqrt [ (10)^2 - (16/2)^2]

= 2 × sqrt [ 100 - 64]

= 2 × sqrt (36)

= 12

Area = 1/2 D1 × D2

= 12 × 16 / 2

= 6 × 16

= 96 cm^2
