Question

The perimeter of a triangular field is 300m abd the ratio of the sides 3:5:7. Find the area of the field​

Answer 1

Answer:

let the ratio of sides be 3x+5x+7x=300m

Step-by-step explanation:

15x/300m

=1/20

then area of the field is 20m

Answer 2

Let the sides of triangular field =3x,5x,7x

A.T.Q

3x+5x+7x=300

15x=300

x=20m

Sides of triangular field = 60m,100m,140m

Area of triangular Field =

S=60+100+140

2

S=150m

By Heron's Formula =√S(S-a)(S-b)(S-c)

=√150×90×50×10

=√6750000

=2598.07m^2
