Question

The length and the breadth of a rectangle are in the ratio 7 is to 4 if the length is doubled and the breadth is increased by 6 and the ratio of the length and the breadth becomes 2 is to 1 find the length and the breadth of the rectangle

Answer 1

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 and breadth is 14 and 8
