Three sides of the park ,
a=120m,b=80m,c=50m
perimeter=a+b+c=(120+80+50)m=250m
Half perimeter (S)=250/2=125m
As the triangle is scalene triangle,
As the triangle is scalene triangle,so the area of the triangle ,
=√s(s-a)(s-b)(s-c) sq.unit
=√125(125-120)(125-80)(125-50) sq.m
=375√15 sq.m
So,he need to plant 375√15sq.m area.
perimeter is 250m.
so ,he have to fence 250m,
it will cost , 250×20=5000Rs.
hope it will help you.
please mark me as brainliest answer.
