Answer:

B is the correct answer

Step-by-step explanation:

  1. Subtract area of triangle from total area: 30 - 14 = 16
  2. Since the figure is a square, all the sides are equal. Therefore, we need to find the square root of 16: √16 = 4
  3. All the sides of the square are 4 cm long

  1. To check, reverse application:
  2. 4 x 4 = 16
  3. 16 + 14 = 30
