Arectangular garden is 6 feet by 4 feet. there is a sidewalk of uniform width around the garden. the area of the sidewalk and the garden together is 48 ft2. what is the width of the sidewalk?

The width of sidewalk is 1 feet.

Step-by-step explanation:

A rectangular garden is 6 feet by 4 feet.

Let sidewalk width be x feet

New length and width of garden including sidewalk width

Length = 6 + 2x

Width = 4 + 2x

Area of sidewalk and garden together is 48

Area of rectangular = L x W

           (6+2x)(4+2x) = 48

x=-6,1

We will ignore negative 6 because width can't be negative

Hence, The width of sidewalk is 1 feet.

think about it deeply and passionately about this property

i am sorry
