Question

The sides of a triangle are in the ratio 5 12 13 and its perimeter is 150 cm its area is

Answer 1

ratio of triangle = 5x,12x,13x

we know that

sum of sides of triangle = perimeter

5x + 12x + 13x = 150

x = 5

sides of triangle

5x = 5*5= 25

12x= 12*5 = 60

13x= 13*5= 65

S= 25+60+65/2

S=75

area of triangle=√75(75-60)(75-65)(75-25)=750 cm

Answer 2

Hello ❤️

Ratio of triangle = 5x, 12x ,13x

We know that sum of sides of triangle = perimeter

5x + 12x + 13 x = 150

X= 5

Sides of triangle :

5x = 5*5 = 25

12x =12*5= 60

13x= 13*5=65

S= 25 + 60 + 65 +/ 2

S= 75

Area of triangle = ✓75(75-60)(75-65)(75-25) = 750M

Hope it will help you ☺️☺️
