Question

The sides of a triangle are in ratio 5 12 13 and it's perimeter is 150m. Find it's area

Answer 1

Answer:

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 M

Answer 2

Answer:

Step-by-step explanation:

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 M
