21:- s= a+b+c/2
s= 5+12+13/2
s= 30/2
s= 15 cm
area= √(s(s-a)(s-b)(s-c))
area=√(15(15-5)(15-12)(15-13))
area=√(15x10x3x2)
area= 5x3x2
area= 30 cm²
Cost =30 x 30
Cost = 900 Rupees
s= 5+12+13/2
s= 30/2
s= 15 cm
area= √(s(s-a)(s-b)(s-c))
area=√(15(15-5)(15-12)(15-13))
area=√(15x10x3x2)
area= 5x3x2
area= 30 cm²
