Answer 1

Answer:

perimeter of triangle = 150m (given) let the sides

of triangle be,a,b and c, on dividing 150 m in the

ratio 5: 12: 13, we get

Step-by-step explanation:

a=5×cm

b=12×cm

c=13×cm

We know that perimeter of a triangle =

sum of all sides =a+b+c

150 =5×+ 13×

× =

150=30×sides are :a

×=5

a

5 12cm b= 12× 60cm

c =13× 65cm
