Adım adım açıklama:
a-) karenin alani = a^2
3,24= lCBl^2 her iki tarafin karekökü alinirsa
lCB= 1,8 cm
b-) karenin cevresi = 4a
2,8= 4.lCBl ise lCBl= 0,7 cm olur
Alan = (0,7)^2= 0,49cm^2
c-) dikdörtgenin alani =a.b
8,75 = 5.lCBl ise lCBl= 1,75 cm
d-) üçgenin alani = lABl.lCHl /2
7,28= 1,4.x /2
2. 7,28= 1.4x
14,56= 1,4x ise x = 10,4 cm
