⠀⠀⠀⠀☛...Given...☚⠀ ⠀

✂⠀The area of rhombus = 72 cm²

✂⠀The one diagonal = 18 cm

⠀⠀⠀⠀☛...To find...☚⠀

✰✰ ⠀Second diagonal of the rhombus...

⠀⠀⠀⠀ ⠀ ⠀⠀ ⠀⠀⠀

⠀⠀⠀ ☛...Solution...☚⠀

We know that...

✂ The area of rhombus =  \dfrac{1}{2}×{d}_{1}×{d}_{2}

  • 72cm² = 1/2 × 18cm × d2
  • 72 = 18/2 × d2
  • 72 = 9 × d2
  • 72/9 = d2
  • 8 = d2

⠀⠀⠀⠀ ⠀ ⠀d2 = 8cm...

Therefore, other diagonal will be 8cm...⠀ ⠀⠀⠀ ⠀⠀
