Question

cum aflu inaltimea in romb stiind ca d1=10 si d2=24 si P=52 cm?

Answer 1

P=52 cm
d1=10cm
d2=24 cm
h=?
Facem astfel:
P=4*l=>l=$\frac{P}{4} = \frac{52cm}{4} =13cm$
l=13 cm
Aflam aria:
A=$\frac{d_{1}*d_{2}}{2} = \frac{10cm*24cm}{2} =120cm^{2}$
Stim formula:
A=l*h=>h=$\frac{A}{l} = \frac{120}{13} =\ \textgreater \ h= \frac{120}{13}$cm
