Question

A triangular park ABC has sides 60 m, 80 m and 100 m. A gardener Ayan has to put a fence

all around it and also plant grass inside. How much area does he need to plant.​

Answer 1

Step-by-step explanation:

let a=60m, b=80m , c=100m

now the area, √s(s-a)(s-b)(s-c)

s=60+80+100=240/2=120 =√120(120-60)(120-80)(120-100)

=2400m^2
