Question

A triangle shaped land as the sides in the ratio 3:5:7: if it is perimeter 300 meter.what will be the area of the land?​

Answer 1

Explanation:

Let the sides of triangle = 3x, 5x, 7x

perimeter = 300m

3x+5x+7x=300

15x=300

x=300/15=20

The sides of triangle=3*20,5*20,7*20

= 60,100,140
