Answer:

20.28 cm²

Step-by-step explanation:

The rectangle on the bottom is 7 cm by 2 cm.

The semicircle has a diameter of 7 cm - 1 cm - 2 cm = 4 cm

diameter = 4 cm

radius = diameter/2 = 2 cm

total area = area of semicircle + area of rectangle

total area = (1/2)πr² + LW

total area = (1/2)(3.14)(2 cm)(2 cm) + 7 cm × 2 cm

total area = 20.28 cm²

Area of rectangle

  • 2(7)
  • 14cm²

Area of semicircle

  • π(7-3/2)²/2
  • (4/2)²π/2
  • 4π/2
  • 12.56cm²/2
  • 6.28cm²

Total area

  • 6.28+14
  • 20.28cm²
