Question

The side of a triangle are in the ratio 3:5:7and it's perimeter is 300cm find it's area​

Answer 1

$\huge\blue{solution}$

Let the sides of a Triangle in Ratio Is 3x 5x 7x

Perimeter of Triangle is 300

$3x + 5x + 7x = 300$

$15x = 300$

$x = \frac{300}{15} = 20$

Therefore, 20 is the answer
