Respuesta:
a) disminuye 4%
Explicación paso a paso:
diagonal mayor disminuye en un 20%.
100% - 20% = 80% = 0.8
diagonal menor aumenta en un 20%.
100% + 20% = 120% = 1.2
Por lo tanto
D = 4 d = 3
A1 = (4x3)/2 = 12/2 = 6
D = 4 x 0.8 = 3.2
d = 3 x 1.2 = 3,6
A2 = (3.2 x 3.6)/2 = 11.52/2 = 5.76
A2/A1 = 5.76/6 x 100 = 96%
100% - 96% = 4%
disminuye 4%
