Răspuns :
2). p triungiului = lat + lat + lat = 5 + 9 +10 = 24 cm
3 ). L = 8
l = 4
p = ?
p = 2 * L + 2* l = 2*8 + 2*4 = 16 + 8 = 24
3 ). L = 8
l = 4
p = ?
p = 2 * L + 2* l = 2*8 + 2*4 = 16 + 8 = 24
ex 2) P = 5 + 9 + 10 = 24 cm
ex 3) P= 2 * ( L+l ) = 2 * 12 = 24 cm
ex 3) P= 2 * ( L+l ) = 2 * 12 = 24 cm
