Hi guys.plz help me out fast with correct answer.

Answer 1

Answer:

the length is 14 cm and breadth is 8 cm.

Step-by-step explanation:

let l be the length of rectangle and b be the breadth of rectangle

=>l:b=7:4

=>l/b=7/4

=>l=7b/4

given length is doubled and the breadth is increased by 6

=>2l/(b+6)=2/1

=>l/(b+6)=1

substitute l=7b/4

=>7b/4=b+6

=>7b=4b+24

=>3b=24

=>b=8

substitute b =8 in l=7b/4

=>l=7(8)/4

=>l=14

so the length is 14 cm and breadth is 8 cm.
