Question

Construct a traingle with perimeter 13 cm and sides are in the ratio 2:3:4 ​

Answer 1

Answer:

Let common multiple be x.

Since the perimeter of traingle is 13cm

2x+3x+4x = 13

9x=13x

X=13/9

The sides of traingles are

2x= 2×13/9= 26/9 = 2.8cm

3x=3×13/9= 13/3 = 4.4cm

4x=4×13/9= 52/9 = 5.7cm

Step-by-step explanation:

Answer 2

ANSWER:

Let the sides be 2x, 3x and 4x

So,

2x+3x+4x= 13 cm

or, 9x= 13 cm

or, x= 13/9

Therefore sides of triangle are

2x= 2×13/9= 2.8 cm

3x= 3×13/9= 4.4 cm

4x= 4×13/9= 5.7 cm

Construction:

Draw a line AB of 5.7 cm

Take A as a center with radius 2.8 cm and draw an arc at point c

With B as a center and 4.4 as a radius draw an arc cutting the pervious arc at point c

Join C to A and B
