നൽകിയത്,

സമചതുർഭുജത്തിന്റെ വിസ്തീർണ്ണം = 96 cm2

ആദ്യത്തെ വികർണ്ണത്തിന്റെ നീളം (d1) = 6 സെന്റീമീറ്റർ

ആശയം:/സൂത്രവാക്യം:

സമചതുർഭുജത്തിന്റെ വിസ്തീർണ്ണം = (1/2) × d1 × d2

d1 = ആദ്യ വികർണ്ണം 

d= രണ്ടാം വികർണ്ണം 

കണക്കുകൂട്ടൽ:

സമചതുർഭുജത്തിന്റെ വിസ്തീർണ്ണം = (1/2) × d1 × d2

⇒ 96 = (1/2) × 6 × d2

⇒ d2 = 96/3

⇒ d2 = 32

രണ്ടാം വികർണ്ണത്തിന്റെ നീളമാണ് 32 cm.
