the length of a rectangular field is 8 meters less than twice it's breadth. if the perimeter of the rectangular field is 56 find its length and breadth
please give the answer as fast as possible
Answers
Answer:
2b - 8 + b = 56 / 2
3b = 36
b = 12
l = 16
❥ The length of a rectangular field is 8 meters less than twice it's breadth. if the perimeter of the rectangular field is 56 find its length and breadth.
❥ The length and Breadth of Rectangle is 16m & 12m respectively.
Perimeter = 56 m.
❥ The length of a rectangular field is 8 meters less than twice its breadth.
Length of the rectangle = ?
Breadth of the rectangle = ?
Here we go !
❥ Let the Unknown Breadth be "x"
Now , as per the question
Length of the rectangle would be
↠ Length of Rectangle ↠ 2x - 8. ..... 1 eqn
❥ Applying formula
↠Perimeter of Rectangle = 2 ( L + B )
↠ 56 = 2 ( 2x - 8 + x )
↠ 56/2 = 2x - 8 + x
↠ 28 = 3x - 8
↠ 28 + 8 = 3x
↠ 36 = 3x
↠ x = 36/3
↠ x = 12
So,
❥ We got the Breadth of Rectangle is 12m.
Now putting it in the eqn ..1
↠ Length of Rectangle
↠ 2x - 8
↠ 24 - 8
↠ 16m
Length
❥ The length of the rectangle is 16m
❥ Breadth of Rectangle is 12m .
