Answer 1

Respuesta:

:)

Explicación paso a paso:

Figura 1

P = 2b + 2h

P = 2(2b + 8) + 2(b - 2)

P = 4b + 16 + 2b - 4

P = 2b + 12

Figura 2

P = L1 + L2 + L3

P = (2d - 3) + (4d + 5) + (2d - 3)

P = 2d - 3 + 4d + 5 + 2d - 3

P = 8d - 1

Figura 3

P = L1 + L2 + L3

P = (2b) + (5b - 3) + (7b + 2)

P = 2b + 5b - 3 + 7b + 2

P = 14b - 1

Figura 4

P = 2L1 + 2L2 + L3

P = 2(2a + 1) + 2(6a - 4) + 4a + 2

P = 4a + 2 + 12a - 8 + 4a + 2

P = 20a - 4
