Question

The sides of a triangle are in the ratio 5:12:13 and its perimeter is 150 cm.Find the area of the triangle in square meter​

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 cm sq.
