◀ Question:◀

A path 2m wide surrounds a garden,20m by 10 m. Find the area of the path and the cost of paving the path at Rs10/m²

◀  Method of Solution:◀

Given: Length of Garden= 20 metre

→  Breadth of Garden= 10 metres

According to the Question's Statement!

→  A Path made surrounds 2 metres Wide,

→  Length of Garden along with path = (20+2+2) = 24 metre

⇒  Breadth of Garden along with path = (10+2+2) = 14 metres

→  Area of Garden = Area of outer Surface of Garden - Area of Inner Surface of Garden

⇒ Area of Garden = (24×14) - (20×10)

[Area of Garden = 136m²]

⇒  Cost of Paving the path = 136 × 10

•°•   → Cost of Paving the Path = Rs. 1360

Hence, Area of the garden and cost of Paving the path are 136m² and Rs. 1360 respectively.→

Answer 2

Hi,


Area of Garden = 24×14 - 20×10


Area = 136

A/Q

Cost = 136×10 = 1360
