Answer:

a) 19 cm

Step-by-step explanation:

Area of a parallelogram: b • h

Given values:

  • A = 228 cm²
  • b = ? cm
  • h = 12 cm

Substitute these values into the formula:

⇒ A = b • h

⇒ 228 = b • 12 [multiply]

⇒ 228 = 12b [divide both sides by 12]

⇒ 228 ÷ 12 = 12b ÷ 12

⇒ 19 = b

Therefore, the base of the parallelogram is 19 cm.
