Answer:

  • 107.125 cm²

Step-by-step explanation:

Find the area of each part and sum up.

Triangle:

  • b = h = 20 - 15 = 5 cm
  • A = 1/2bh = 1/2*5*5 = 12.5 cm²

Rectangle:

  • A = 5*15 = 75 cm²

Quarter-circle:

  • A = 1/4πr² = 1/4*3.14*5² = 19.625 cm²

The sum is:

  • 12.5 + 75 + 19.625 = 107.125 cm²
