Question

find the area of a triangle whose side are in the ratio 5:12:13 and its perimeter is 60 cm​

Answer 1

Answer:

Step-by-step explanation:

perimeter=sum of the sides

60=5x+12x+13x

60=30x

x=60/30=2

sides=10,24,26

s=10+24+26/2

s=60/2=30

area = sqrt(s x (s-a)(s-b)(s-c))

area= sqrt(30 X 20 X 6 X 4)

area= sqrt(14400)

area = 120 cm^2
