Question

Side of triangular field are 41 m 40 m and 9m find the area

Answer 1

Hii friend,

Let A = 41 m , B = 40 m , C = 9m

Therefore,

S = 1/2 ( A+B+C)

= 1/2 ( 41+40+9) = 1/2 × 90 = 45 m

Therefore,

S-A = 45-41 = 4 m

S-B = 45-40 = 5 m

S-C = 45-9 = 36 m

Therefore,

Area of triangle = ✓ S(S-A)(S-B)(S-C)

= ✓45×4×5×36

= ✓32400 = 180 M².


HOPE IT WILL HELP YOU...... :-)

Answer 2

use the herons formula

a+b+c/2=s

area= under 4oots(s-a) (s-b)( s-c)
