Hi,

Area of garden & path = 225
Side = $$\sqrt{225}$$ = 15 ft

As per the below diagram,
Attachment:

Side of garden = 11 ft

When sides of garden are increased by 5 ft,
new dimension = 11+5 = 16 ft
Area = $$16^2$$ = 256

Thanks.

I missed to take 2 feet on both sides. so took the side of the garden as 15-2 =13.

so 13 +5 after increasing and the area of garden as 18^2 = 324.

Have to be careful . Thanks for the solution.

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

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.
