ayuda porfa ​

Answer 1

Respuesta:

a)  1,759.45cm^2

b)  1,548.75mm^2

c)  1,391.175dm^2

Explicación paso a paso:

a)

2 formulas

Perimetro = 22cm*7= 154cm

Area = (154cm*22.85cm)/2 = 3,518.9/2 = 1,759.45cm^2

o

Area = ((22.85*22)/2)*7 = (502.7/2)*7 = 251.35*7 = 1,759.45cm^2

b)

Area = ((20.65*30)/2)*5 = (619.5/2)*5= 309.75*5 = 1,548.75mm^2

c)

Area = ((20.61*15)/2)*9 = (309.15/2)*9= 154.575*9 = 1,391.175dm^2
