Question

Fine the are if a triangle whose sides are in ratio of 5:12:13 and it's perimeter is 60cm​

Answer 1

Step-by-step explanation:

perimeter of triangle = sum of all sides

5x+12x+13x=60

30x = 60

x = 20

so first side is 5*20 = 100

12*20 = 240

30*20 = 600

Answer 2

Answer:

x=2

Area=312cm^2

Step-by-step explanation:

Let the ratios be 5x,12x,13x

Perimeter=60cm

Perimeter of a triangle=a+b+c

ATP

5x+12x+13x=60

30x=60

x=60/30

x=2

Length=5*2

=10cm

Breadth=12*2

=24cm

Height=13*2

=26cm

Area=1/2*24*26

=12*26

=312cm^2
