Question

Ayudaaaa porfaaa! solo es el primer ejercicio y ya no sé hacerlo, a la respuesta que esté bien, le daré gracias, corona y estrella

Answer 1

a) Al = 2L (E+A)

Al = 2 (8) (5+4)

Al = 16 (9)

Al = 144 m^2

At = Al + 2LA

At = 144 + 2 (8) (4)

At = 144 + 2 (32)

At = 144 + 64

At = 208 m^2

b) Al = 6 (b × h)

Al = 6 ( 12 × 4)

Al = 288 cm^2

Apotema => 4^2 = a^2 + 2^2

16 = a^2 +4

16 - 4 = a^2

12 = a^2

√12 = a

3,464 = a

Abase = P × a / 2

Abase = (6 ×4) × 3,464 / 2

Abase = 24 × 3,464 / 2

Abase = 41,568 cm^2

At = 2 × Ab + Al

At = 2 × 41,568 + 288

At = 83,136 + 288

At = 371, 14 cm^2

c) Al = 4 L^2

Al = 4 (9)^2

Al = 4 (81)

Al = 324 cm^2

At = 6 L^2

At = 6 (9)^2

At = 6 (81)

At = 486 cm^2

Ojalá te haya ayudado. Saludos.
