Question

find the area of a triangle whose sides are in the ratio 5 : 12: 13 and its perimeter is 60 CM.

Answer 1

HEYA!

5x+12x+13x=60

30x=60

x=60÷30

x=2

5x=10

12x=24

13x=26

then you can find the area using heron's formula

that would be 120 cm square

HOPE THIS HELPS

:)

Answer 2

let sides be 5x,12x,13,
Thus 5x+12x+13=60
=>x=2
THUS
Sides are 10,24,26cm
