Question

plese solve this question​

Answer 1

Let the width of the garden be x

Therefore, the length of the garden = x + 4

Now,

Perimeter of a rectangle =  2 (l +b)

∴ Half the perimeter = l + b

∴ 36 = (x + 4) + x

⇒ x + x + 4 = 36

⇒ 2x  =   36 - 4

⇒ 2x  =   32

⇒  x   =    16

∴Width of the garden = 16 m

And,  Length of the garden = 16 + 4

                                              =  20 m         Ans.

Hope it will help you...............

Answer 2

Answer:

perimeter =2(l+b)

half perimeter 36m=(l+b)

let breadth=x

length=4x

perimeter=2x36=72m

perimeter=2(l+b)

72=2(4+x+x)

36=4+2x

36-4=2x

32=2x

32/2=x

16=x

breadth=16

length=x+4=16+4=20
