Question

A square swimming pool is of side 35 m a path of width is 1.5 m runs around it. find the area of the path.​

Answer 1

Step-by-step explanation:

definition of specific heat capacity of any substance is “the quantity of heat required to change the temperature of a unit mass of the substance by 1 degree.” This is articulated as:

Answer 2

Answer: Consider the side of the lawn be x

Given width of the path 2.5m

Side of the lawn including path x+2(2.5)=x+5

Area of a square  =(side)

2

So, area of lawn = (Area of the lawn including the path) - (Area of the path)

Therefore, According to the given question,:

 x

2

=(x + 5)

−165

  x

2

=(x

2

 + 10x +25)−165m

=x

2

+10x+25−165

  x

=x

2

 +10x−140

  x

2

 −140=x

2

−10x

  x

2

−x

2

−140=−10x

 −140=−10x

 i.e 140=10x

  ∴x=140/10=14

Since the side of the lawn = 14m

The area of the lawn=(14)
