Find the area of triangle having sides 12 cm 16 cm and 20 cm calculate also the width of the correct angle of same area as a triangle having its length is 15 cm

answer:

12+6+15 cm

=33cm

it is answer

answer:

Area of Triangle = Sum of all side

= (12+6+15)cm square

= 33cm square

Hope this helps uhh mate.....

Let a = 10 cm., b = 12 cm., c = 14 cm.

Area ir the triangle =

√

s(s−a)(s−b)(s−c)

s=

a+b+c

2

=

10+12+14

=

36

=18

Area of the triangle =

√

18(18−10)(18−12)(18−14)

=

√

18×8×6×4

=

√

9×2×8×6×4

==3×4×26–√=246–√ sq.cm.

Plus these numbers then you will get the answer

answer:

first of all change x-3y and x+3y.then again change xsquare +9ysquare and again change the remaining with the result your answer will be there.hope it is for you
