Question

the perimeter of a triangle is 60 cm .if its sideare jn the ratio 1:2:3 then its smaller side is
​

Answer 1

Answer:

Perimeter of the Triangle =60cm

Let the ratio of sides be x, 2x and 3x

ATQ

X+2x+3x=60

6x=60

X=60/6=10

The measure of sides=x=10cm, 2x=2×10=20cm and 3x=3×10=30cm

Clearly, the smaller side =10cm

Answer 2

Answer:

perimeter of the triangle = 60 cm

60=1x+2x+3x

60 cm =6x

60/6=x

10=x

therefore, the smaller side is 10cm
