Answer :
according to HERO`S LAW , area of triangle is
√[s(s-a)(s-b)(s-c)]
where , s = semiperimeter
a,b,c = length of the edges
so the area becomes
√(3x × x × x × x)
= √3 x² cm²
√[s(s-a)(s-b)(s-c)]
where , s = semiperimeter
a,b,c = length of the edges
so the area becomes
√(3x × x × x × x)
= √3 x² cm²
