Answer:

See below ~

Explanation:

#7)

  • Area of a rectangle = l x b
  • 30 in² = 4 in (x in)
  • x = 30/4 = 7.5 inches

#8)

  • Total Surface Area = 2 x Area (Triangle) + Area (Rectangle 1) + Area (Rectangle 2) + Area (Rectangle 3)
  • TSA = 2 x 1/2 x 3 x 4 + 9 x 5 + 4 x 9 + 3 x 9
  • TSA = 12 + 45 + 36 + 27
  • TSA = 57 + 63
  • TSA = 120 in²
