Question

the width of the room is two third of its length. if the width had been 30 cm more and length 30 cm less it would have been a square . Find the length and breadth .​

Answer 1

Answer:

L=180 CMS, W=120CMS

Step-by-step explanation:

GIVEN L=SOME x

and w=2/3 (L)

from this we can say 1/3 is diff between L AND w

given width incrased by 30 and length decreased by 30 makes it sqaure

range for width and length =60 (30+30)

if 1/3 =60

then 1=?

(1*60)/1/3=180

L=180

w=2/3(180)=120

for proof increase and decrease width and lenght by 30 respectively to get a sqaure .which is 150*150

thus L=180 CMS, W=120CMS....

pls mark as brainliest for my effort
