Question

Half the perimeter of a rectangular garden,whose length is 4 m more than its width,is 36 m.Find the dimensions of the garden​

Answer 1

Perimeter = 2(l+b)

1/2 Perimeter = 1/2 × 2 ( l+b)

1/2 Perimeter= (l+b)

taking width as x then length will be 4+x

So,

36= (x+4+x)

36= ( 2x +4 )

36-4/2= x

16= x

Dimensions of gardern are 16 and 16+4= 20
