Question

can you construct a triangle whose perimeter is 12cm and the ratio of its sides is 1:2:3​

Answer 1

Step-by-step explanation:

12 cm=120 mm

sum of ratio will be 1+2+3=6

let the number be x

$6x = 120 \\ or \: x = \frac{120}{6} \\ or \: x = 20$

measure of side 1 = 1×20 = 20mm = 2cm

measure of side 2 = 2×20 = 40mm = 4cm

measure of side 3 = 3×20 = 60mm = 6cm

measure of sides will be 2cm, 4cm, 6cm

hope this helps
