Question

A rectangular garden is surrounded by a path of uniform width 3m. If breadth of the garden is 40m and area of the path is 588m², find the length of the garden.​

Answer 1

Answer:

52 m

Step-by-step explanation:

• Width of the path = 3 m
• Breadth of the garden = 40 m
• Length of the garden = x
• Area of the path = 588 m²

Area of the path is the difference of the of full area and the area of the garden.

Full area will have the sides:

• 40 + 3*2= 46 and
• x + 3*2 = x + 6

Area of the garden is

• 40*x

So the difference is:

• 588 = (x + 6)*46 - 40*x
• 588 = 46x + 6*46 - 40x
• 588 = 6x + 276
• 6x = 588 - 276
• 6x = 312
• x = 312/6
• x = 52 m

The length of the garden is 52 m
