Question

2.Half the perimeter of a rectangular garden is 40 m. length is 4 m more than its width. Find the dimensions of the garden​

Answer 1

Step-by-step explanation:

perimeter = 2(l+b) where l is length and b is breadth

half of perimeter = (l+b)

let b=x then l=x+4(acc to que.)

x+ x+4=40

2x =36

x =18. length = 22 , breadth=18

Answer 2

Answer:

The width and the length of the

rectangular garden is 18 m and 22 m. respectively.

Step-by-step explanation:

Let,

• The width of the rectangle = x
• The length of the rectangle = x + 4

• Half the perimeter of a rectangular garden is 40 m. (Given)

★ According to the Question :

⇒ Half the perimeter = (length + width)

⇒ 40 = [(x + 4) + x]

⇒ 40 = 2x + 4

⇒ 40 - 4 = 2x

⇒ 2x = 36

⇒ x = 36/2

⇒ x = 18

The width of the rectangle = 18 m

• The length of the rectangle = x + 4

⇒ 18 + 4

⇒ 22

The length of the rectangle = 22 m

Therefore, the width and the length of the rectangular garden is 18 m and 22 m. respectively.
