Question

plsssss! dau coroanaaaaa​

Answer 1

Răspuns:

2.A=?

A=$l^{2}$

P=24$\sqrt{2}$=4*l  => l=($24\sqrt{2}$)/4=6$\sqrt{2}$cm

=>A=$(6\sqrt{2}) ^{2}$=36*2=72$cm^{3}$

3. P=30cm =>l=10cm

A=($l^{2}$$\sqrt{3}$)/4=(100$\sqrt{3}$)4=25$\sqrt{3}$ $cm^{3}$

6. d1=40cm, d2=30cm

h=2,4dm=24cm

A=(d1*d2)/2=(40*30)/2=600 cm cub

A=l*h =>l=A/h=600/24=25cm
