Question

area of a triangle of sides 12, 12, 6 step by step herons formula​

Answer 1

Step-by-step explanation:

Area of triangle =1/2×base×height

=1/2×12× h

Answer 2

Answer:

Area = 9√15cm^2

Step-by-step explanation:

a=12cm, b=12cm, c=6cm

s = (a+b+c)/2

= (12+12+6)/2

= 30/2

= 15cm

Area = √s(s-a)(s-b)(s-c)

= √15(15-12)(15-12)(15-6)

= √15×3×3×9

= √5×3×3×3×3×3

= 3×3√5×3

= 9√15cm^2
