Question

Side of triangle are in the ratio 3:4:5 perimeter is 360 m find its area

Answer 1

Answer:

let the sides be 3x 4x 5x

therefore 12x= 360

x= 30

sides are 90 120 and 150

these forms the pythagorean triplet

therefore it is a right triangle

area= 1/2×90×120

=5400

Answer 2

$\sf \: As \: we \: know \: \\ \\ \sf \: Perimeter \: of \: triangle = Sum \: of \: all \: sides \\ \\ \sf 3x + 5x + 4x = 360 \\ \\ \sf12x = 360 \\ \\ \sf \: x = \frac{360}{12} \\ \\ \sf x = 30 \\ \\ \sf \: So, \: sides =90,150,120$
