Question

find the area of the trianglr whose sides are 13cm 9 cm 6cm

Answer 1

to find the area of a triangle having sides of different lengths, we use the hero's formula ie√s(s- a)(s-b)(s-c)
so for finding "s" we will add all the sides and will devide it by 2
13+9+6/2=14
now we will put the formula
√14(14-13)(14-9)(14-6)
√14×1×5×8
√560
√7×2×5×2×2×2
=4√35
I hope this will help you.

Answer 2

HELLO MY DEAR FRIEND

THE GIVEN SIDES OF A TRIANGLE = 13 CM, 6CM, AND 9CM.

THE AREA OF A TRIANGLE = 1/2 *BASE * HEIGHT.

HERE LETS TAKE THE BASE AS 13 CM
AND HEIGHT = 9CM.

= 1/2*BASE*HEIGHT
= 1/2*13 cm* 9cm
= 1/2*117cm
= 58.5 cm square.
I THINK MY ANSWER IS CORRECT.

I HOPE THIS WILL HELP'S U..............*-*
