Answer:

Lateral surface area = 36 ft²

Step-by-step explanation:

Formula:

Lateral surface area = perimeter of the base × height

………………………………………………………………

perimeter of the base = 2×(1.5+3) = 9

height = 4.

then

Lateral surface area = 9 × 4 = 36

Area of two bigger rectangles

  • 2LB
  • 24(3)
  • 2(12)ft²
  • 24ft²

Area of two smaller rectangles

  • 2×1.5(4)
  • 2×6
  • 12ft²

LSA

  • 12+24
  • 36ft²
