Question

the perimeter of triangular field is 300m and the ratio of the sides is 3:5:7 find the area of the field

Answer 1

Answer:

2598.07m^2

Step-by-step explanation:

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
