Answer:

  • 102 cm

Step-by-step explanation:

  • Diagonals of a rhombus are perpendicular.
  • Sides are of equal length.

<u>Use Pythagorean to work out the side length.</u>

  • a² = (d₁/2)² + (d₂/2)²
  • a² = (24/2)² + (45/2)² = 650.25
  • a = √650.25
  • a = 25.5 cm

<u>The perimeter is:</u>

  • P = 4a
  • P = 4*25.5 = 102 cm
