Question

If the breadth of a rectangle is subtracted from twice the length , then it is equal to 27 .And if the breadth of a rectangle is 5 / 7 times of the length . Then find the length of the rectangle. ​

Answer 1

Answer:

the length of the rectangle is 21

Step-by-step explanation:

let length and breadth of the rectangle be x and y respectively,

2x - y = 27

so y= 2x-27

if breadth of the rectangle is equal to 5/7 times the length ,

y=5/7 x

substituting the value of y,

2x-27= 5x/7

simplifying the equation, we get

9x=189

which means the value of x is 21

therefore the length of the rectangle is 21
