The area of the triangle = (1/2)* base * height
= (1/2)* 8*6= 24 m^2
The area of circle = π(2)^2 = 4π= 12.56 m^2
The area used for growing roses = 24-12.56= 11.433 m^2
Hope this helps.

it's wrong.. kindly correct it. it's not given that it is a right angle triangle and height is this ir base is this.. u have to find the area by heron's formula
Hi, The Length of the sides are given as 6,8,10.
√6^2+8^2 =10.
they are called traids.
they form a right angle triangle.
hope it cleared you confusion.
sorry.. i dunno
No problem.

Answer:
Semiperimeter of triangular park = (8+10+6)/2 = 12m.
Area of triangle heron's formula = Root {12(12-8)(12-10)(12-6)} = 24m2
Area of circle to be left out = Pie X (2/2)2 = 3.14m2
Area used for growing grasses = Total area - area to be left out
= 24m2 - 3.14m2 = 20.86m2
