Odpowiedź :
a)
2√3*5√3 = 30cm²
b)
3√2*½2√2 = 6cm²
c) (2√5+3√5)*√15/2 = 5√5*√15/2 = 10√3/2 = 5√3
2√3*5√3 = 30cm²
b)
3√2*½2√2 = 6cm²
c) (2√5+3√5)*√15/2 = 5√5*√15/2 = 10√3/2 = 5√3
a) a*b=2√6 * 5√3=10√18=10*3√2=30√2
b)a*h= (2√2+√2) *2√6/3=2√12=4√3
c)0,5**(a+b)*h=0,5* (2√5 + 3√5)*√15=0,5*5*15=37,5
b)a*h= (2√2+√2) *2√6/3=2√12=4√3
c)0,5**(a+b)*h=0,5* (2√5 + 3√5)*√15=0,5*5*15=37,5
