Step-by-step explanation:
by herons formula,we have area of triangle
=√s(s-a)(s-b)(s-c)
here s=11+15+18/2
s=44/2
s=22cm
ara=√22(22-11)(22-15)(22-18)
=√22(11)(7)(4)
=√12216
=√(12) (216)
= √4×3( 16) square
= 96sq.cm
the largest side=1/2×base(largest side)x attitude=96cm square.
1/2×18× attitude= 96cm square
attitude= 2/1×1/1= 6×1/16cmm
