   Parallelogrammning tomonlari A va B bo’lsa, uning bitta diagonali orqali
   

bo’linishidan hosil bo’lgan uchburchaklar yuzalarini toping. (2 ta Label, 2 ta TextBox, 1 ta Button. Natija Labelda chiqarilsin)

6. Teng tomonli uchburchakka ichki chizilgan doira yuzi S berilgan bo’lsa, uchburchak
medianasi va balandligini toping. (3 ta Label, 1 ta TextBox, 1 ta Button. Natija Labelda
chiqarilsin)
7. Noldan farqli a son va b son berilgan. ax+b=0 tenglamani yeching. ( 2 ta Label, 2 ta TextBox, 1 ta Button. Natija Labelda chiqarilsin)
