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.
