Answer:

#1

The scale factor is:

  • k = 10/4 = 2.5

The scale factor of the area:

  • k² = (2.5)² = 6.25

Area of the larger pentagon:

  • 27.5*6.25 = 171.875 ≈ 172 cm²

Correct choice is B

#2

The scale factor, the ratio of corresponding sides:

  • XZ/AC = 9/6 = 1.5

Perimeter of ABC:

  • 3 + 6 + 8 = 17

Perimeter of XYZ:

  • 17*1.5 = 25.5 units

Correct choice is C

#22

  • P(RST) = 57
  • k = 3/2
  • P(RST) / P(HKN) = 3/2
  • 57 / P(HKN) = 3/2
  • P(HKN) = 57*2/3 = 38 feet
