Question

the sides of the triangular field is in the ratio 13:12:5 and its perimeter is 900m find the area of the field and also find the cost of ploughing the field at the rate of Rs 25/msquare

plsssss help its urgent ​

Answer 1

Step-by-step explanation:

let the common multiple =x m

1st side=13x m

2nd side=12x m

3rd side =5x m

atq,

13x+12x+5x=900

30x=900

x=30

therefore, x=30 m

1st side=13*30=390m

2nd side=12*30=360m

3rd side=5*30=150m

area of the field =27000 m square (by herons law)

cost of ploughing =27000*25=675000 rupees
