Question

find the area of a triangle whose sides are in ratio 5:12:13 and it's Perimeter is 60 cm
​

Answer 1

Step-by-step explanation:

5x+12x+13x=60

30x=60

x=60÷30

x=2

5x=10

12x=24

13x=26

x=2cm

hence

5x=10 =a

12x=24 = b

13x=26 = c

HERON'S FORMULA

AREA OF TRIANGLE = √s(s-a)(s-b)(s-c)

s= perimeter /2 = 30

AREA OF TRIANGLE = √s(s-a)(s-b)(s-c)

=√30(30-10)(30-24)(30-26)

=√3*10*2*10*2*3*2*2

=√3*3*10*10*2*2*2*2

=3*10*2*2

AREA OF TRIANGLE = 120 cm
