12i - 3i^2 + 6 + 2i
-3i^2 + 14i + 6
Four point one nine three. Answer
Answer:
169 cm^2
Step-by-step explanation:
Right surface (rectangle)
A = LW = 7 cm * 5 cm = 35 cm^2
Left surface (hidden rectangle)
A = LW = 7 cm * 5 cm = 35 cm^2
Bottom surface (hidden rectangle)
A = LW = 9 cm * 5 cm = 45 cm^2
Front face = back face = 2 * triangle
A = 2 * bh/2 = 2 * 9 cm * 6 cm/2 = 54 cm^2
total surface area = 35 cm^2 + 35 cm^2 + 45 cm^2 + 54 cm^2 = 169 cm^2
