Answer 2

Answer:

The amount to be paid to the gardener is Rs.504

Step-by-step explanation:

Here, length of the sides of park are 30m,26m,28m.

Let us denote the length of the sides as :-

a = 30m

b = 26m

c = 28m

So, S = a+b+c/2

Therefore, S = 30+26+28/2

= 84/2

= 42m

Therefore, Area of the triangular park

= root over of s(s-a)(s-b)(s-c)

= root over of 42(42-30)(42-26)(42-28)

= root over of 42×12×16×14

= 336 m^2

The amount to be paid to the gardener = Rs.(336×1.50)

= Rs.504
