Question

construct a triangle whose sides are in the ratio 1 ratio 3 ratio 5 and whose perimeter is 18 cm ​

Answer 1

Step-by-step explanation:

let the sides be x 3x and 5x

so we have

x +3x+5x=18

9x=18

x=18/9

x=2

so the sides are 2cm,6cm and 10cm

Then,

draw a line AB of 6cm

with A as centre cut an arc of 10cm and with B as centre cut an arc of 2cm
