Question

construct a triangle whose sides are in the ratio 2 ratio 3 ratio 4 and whose perimeter is 18 cm

Answer 1

Answer:

Step-by-step explanation:

Let the side be 2x, 3x, 4x respectively

now 2x+3x+4x = 18

9x = 18

x=2

honce side are 4cm 3cm and 8 cm

draw BC= 8cm

From B draw an arc with radius 3cm

From C draw an arc with radius 4cm which meet previous arc at A

join AB & AC

Thus ABC is required triangle

Answer 2

hey friend


here your answer
___________________________


perimeter of triangle = 18 cm


a:b:c = 2:3:4


$\: \: a = \frac{2(18)}{2 + 3 + 4} \\ \\ \\ \: \: \: \: \: \:= \frac{36}{9} = 4 \: cm \\ \\ \\ \: \: \: \: \: b = \frac{3(18)}{2 + 3 + 4} \\ \\ \\ \: \: \: \: \: \: \: \: = \frac{54}{9 } = 6 \: \: cm \\ \\ \\ \: \: \: \: \: \: \: c = \frac{4(18)}{2 + 3 + 4} \\ \\ \\ \: \: \: \: \: \: \: \: \: = \frac{72}{9} = 8 \: cm \\ \\ \: \: \: \: \\ \: \: \: \: \: hope \: it \: helps \: you$
