Question

vă rog ajutați-mă
am nevoie și de formula ei ​

Answer 1

S1 = L1* l1 = 25.8*20.3= 523.74cm^2

S2= L2* l2=26*20.5=533cm^2

S3= L3* l3=26.2*20.5=537.1cm^2

S4= L4* l4=25.9*20.2=523.18cm^2

Sm = (S1+S2+S3+S4)/4 = 2117.02/4=529.255cm^2

ΔS1=|Sm-S1|=|529.255-523.74|=5.515cm^2

ΔS2=|Sm-S2|=|529.255-533|=|-3.745|=3.745cm^2

ΔS3=|Sm-S3|=|529.255-537.1|=|-7.845|=7.845cm^2

ΔS4=|Sm-S4|=|529.255-523.18|=6.075cm^2

ΔSm=(ΔS1+ΔS2+ΔS3+ΔS4)/4=(5.515+3.745+7.845+6.075)/4=5.795cm^2
