Question

The sides of triangular plot are in ratio 3:5:7 and perimeter is 300m Find its area​

Answer 1

Answer:

let the sides be 3x,5x,7x.

then , 3x+5x+7X = 300

        15x = 300

          x = 20

        3x = 60m

         5x = 100m

          7x = 140m

to find area use the herons formula,

a, b,c are the sides

s = a+b+c / 2

Area = root [s(s-a)(s-b)(s-c)

        =2598 m^2   (approx)
