Answer:

70%

Step-by-step explanation:

Finding each side :-

  • 4a = 20m
  • a = 5 m

Finding area of unshaded region :-

  • A = 1/2 * b * h
  • A = 1/2 * 1.5 * 5 cm²
  • A = 2.5 * 1.5 cm²
  • A = 3.75 cm²

  • Total unshaded region = 2*3.75 = 7.5 cm²

Overall area :-

  • A = a²
  • A = (5cm)²
  • A = 25m²

Finding percentage :-

  • % = 25 - 7.5 / 25 * 100
  • % = 17.5 * 4
  • % = 70
