7=c(s) obviously
c = 7
7 = Continents of the World
16.5
Let s = semiperimeter (ie half the perimeter) So s = (a+b+c)/2 = (5 + 8 + 11)/2 = 24/2 = 12 Then area = sqrt[s*(s-a)*(s-b)*(s-c)] = sqrt[12*7*4*1] = sqrt[336] = 18.33 square units.
7 = Swans a-swimming
13 = 7 + s(13 - 7) = (7-7) + s6 = s
c = 6 and d = 7
The ditloid 7 equals B for S B (7 = B for S B) means:7 = Brides for Seven Brothers
7 equals down in sewer water
To find this: You know (B+C) = 7. Therefore you know (A+A )= 21 - (B+C). Therefore 21-7 = 14. So now you know (A+A) = 14. So you divide (A+A)/2. This equals 7. Therefore A = 7.
the answer is a
Colours in the Rainbow
