Re: A square garden is surrounded by a 2 feet wide walkway on [#permalink]

Let 'x' be the side of garden excluding the walkway.
Thus side of garden including the walkway = (x+4) (since its 2 feet on both sides)

Area = (x+4)^2 = 225 Or (x+4) = 15 Or x = 11

Right now side of square garden is 11 feet. New side = 11+5 = 16 feet
New Area = 16*16 = 256 sq feet

Hence D answer

Solution



Given:
    • A square garden is surrounded by a 2 feet wide walkway on each side.
    • The area of the garden and the walkway is 225 square feet.
    • Garden is broadened by increasing side of the garden by 5 units.

To find:
    • Area of the garden if the garden is broadened by increasing side of the garden by 5 units.

Approach and Working

    • Let the side of the garden is x feet.
      o Hence, the side of garden +walkway= l+4 feet
      • \((x+4)^2\)= 225
        o x= 11
      • x+5= 16
      • \((x+5)^2\)= 256 feet.

Correct answer: Option D

A. 121
B. 169
C. 225
D. 256
E. 324

Solution:

A side of the garden, including the walkway, currently is √225 = 15 ft. Without the walkway bordering the garden, the length of a side of the garden is 15 - 2 - 2 = 11 ft. Thus, when the side of the garden is increased by 5 ft, the area of the garden would be (11 + 5)^2 = 16^2 = 256 sq. ft.
