Question

Find the total area for the regular pyramid. T. A. =

Answer 1

The total area is:
 A = Ab + Al
 Where,
 Ab: base area
 Al: lateral area
 We have then:
 For the base area:
 Ab = (2) * (2)
 Ab = 4 units ^ 2
 For the lateral area:
 Al = (4) * (1/2) * (2) * (root ((1) ^ 2 + (3) ^ 2))
 Al = (4) * (root (1 + 9))
 Al = 4raiz (10) units ^ 2
 Total area:
 A = 4 + 4raiz (10)
 Answer:
 A = 4 + 4raiz (10)

Answer 2

The answer to this is: A = 4 + 4raiz (10)

Formula: A = Ab + Al Where, Ab= base area A= lateral area


 For the base area: Ab = (2) * (2) Ab = 4 units ^ 2

 For the lateral area: Al = (4) * (1/2) * (2) * (root ((1) ^ 2 + (3) ^ 2)) Al = (4) * (root (1 + 9)) Al = 4raiz (10) units ^ 2

 Total area: A = 4 + 4raiz (10)
