Question

the side of a triangular plot are in the ratio of 3:5:7 and its area perimeter is 300m.find its area​

Answer 1

Answer:

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

3x + 5x + 7x=300

15x = 300

x = 300/15

x = 20

so, 3×20 = 60

5×20 = 100

7×20 = 140

Answer 2

Answer:

Step-by-step explanation:

Let the ratio be x

3x+5x+7x = 300m

15x = 300m

X= 20

5x =5×20=100m

3x = 3×20=60 m

7x=7×20= 140m

Then u can solve it by heron's formula
