Question

The perimeter of a triangular field is 450 m and its sides are in the ri 13:12:5. The area in m2) of the triangular field is 30k
then find the value of √k.​

Answer 1

Answer:

√15

Step-by-step explanation:

perimeter of triangle = sum of all sides

450=13x(+)12x(+)5x (taking 13x,12x,5x)

450=30x

x=450/30

x=15

now,

value of x is 15 so,multiply all no. with 15,

13*15=195

12*15=180

5*15=75

area of triangle = 1/2*base*hight

30k=1/2*180*75

30k=90*75

30k=6750

k=6750/30

k=225

you want answer in root so,

k=√225

k=15²

hence the value of K is 15.
