1.	if the length and breadth of rectangle is 1:3. when the length and breadth are both increased by 5 units. the ratio becomes 4:7. find the length and breadth of the rectangle
Answer» Answer: Step-by-step EXPLANATION: The RATIO of length and breadth are in ratio 1:3 l=x ,b=3 x If both are INCREASED by 5 l=x+5 ,b=3 x+5 x+5/3 x+5=4/7 7 x+35=12 x+20 12 x-7 x=35-20 5 x=15 x=15/5 x=3 units length =3 ,breadth=3*3=9

if the length and breadth of rectangle is 1:3. when the length and breadth are both increased by 5 units. the ratio becomes 4:7. find the length and breadth of the rectangle

Answer»

Answer:

Step-by-step EXPLANATION:

The RATIO of length and breadth are in ratio 1:3

l=x ,b=3 x

If both are INCREASED by 5

l=x+5 ,b=3 x+5

x+5/3 x+5=4/7

7 x+35=12 x+20

12 x-7 x=35-20

5 x=15

x=15/5

x=3 units

length =3 ,breadth=3*3=9
