If p:q=1:2 and q:r=4:3,find p:q:r​

2:4:3

Step-by-step explanation:

To Find :-

Solution :-

By question ,

→ p :q= 1:2

→ q : r = 4 :3

Therefore ,

→ p/q × q/r = 1/2 × 4/3

→ p/r = 2/3

Again ,

→ p = 1/2q

→ r = 3/4 q

Henceforth ,

→ p : q : r

→ 1/2 q : q : 3/4q

→ 4/2q : 4q : 12/4 q

→ 2 : 4 : 3

hello! just here for points! though i wish i knew!

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
