# The sides of a tr

Given sides of triangular field = 41m, 40m and 9m.

= Total number of flower bed =

We know Area of one flower bed = 900cm2 = 0.09m2

Sides of triangular field are a = 41m, b = 40m, c = 9m.

by Heron’s formula, we get the area of triangle

=

(where s = s is called as the semi perimeter )…(1)

we get

Substituting the value of s, a, b and c in equation 1 we get

=

=

The area of the triangular field is .

Total number of flower bed =

=

Total number of flower beds that can be placed is 2000.
