Răspuns:
a)1500[tex]\sqrt{11}[/tex] [tex]m^{2}[/tex]
b)19345 kg
Explicație pas cu pas:
a) h=[tex]\sqrt{3600-2500}[/tex]=10[tex]\sqrt{11}[/tex]
Aria= (B+b)/2*h=(200+100)/2*10[tex]\sqrt{11}[/tex]=1500[tex]\sqrt{11}[/tex] [tex]m^{2}[/tex]
B-Baza mare
b-baza mica
h-inaltimea
b) 1750 kg ..... 1500 [tex]\sqrt{11}[/tex][tex]m^{2}[/tex]
x kg .......... 5000 [tex]m^{2}[/tex]
x= 1750*5000/1500 [tex]\sqrt{11}[/tex]=19345 kg
