52 m

69 m²

2.

78 m

198 m²

3.

58 m

78 m²

Explicación paso a paso:

1.

P = 3 + 5 + 5 + 3 + 5 + 5 + 3 + 5 + 5 + 3 + 5 + 5 = 52 m

A = (3 * 5) + (3 * 5) + (3 * 5) + (3 *5) + (3 * 3) = 69 m²

2.

P = (13 + 3 + 5 + 18) * 2 = 39 * 2 = 78 m

A = (13 * 3) + (13 * 3) + (15 * 8) = 39 + 39 + 120 = 198 m²

3.

P = 2 + 7 + 6 + 7 + 2 + 12 + 10 + 12 = 58 m

A = 2 (7 * 2) + (10 * 5) = 28 + 50 = 78 m²
