Answer:

64 cm

Step-by-step explanation:

you remove 2 cm on length on both sides so you have to remove 4 cm,then the length is 16 cm.

as for wide it is 8 cm you remove 2 cm on each sides it becomes 4 cm. The area of a RECTANGLE is l×b that is 16×4=64

Answer :

Here, we are given the dimensions, i.e. length and breadth of a rectangular garden. Also, we are given the width of the path running all around inside the garden. We need to calculate the area of the path. So, for that firstly we will find the dimensions of the path by subtracting (2 + 2) cm from the dimensions of the rectanglular garden. And then by using the formula of area of rectangle, we will calculate the area of path.

Solution :

Given :

• Length of the rectangular garden = 20 cm

• Breadth of the rectangular garden = 8 cm

• Width of the path running all around the garden = 2 cm

To find :

• Area of the path

Required solution :

Calculating the dimensions of the path :

⇒ Length of path = Length of rectangular garden - 2(Width of the path)

⇒ Length = 20 - (2 + 2)

⇒ Length = 20 - 4

⇒ Length = 16 cm

⇒ Breadth of path = Breadth of rectangular garden - 2(Width of the path)

⇒ Breadth = 8 - (2 + 2)

⇒ Breadth = 8 - 4

⇒ Breadth = 4 cm

Hence,

  • Length of the rectangular garden including path = 16 cm
  • Breadth of the rectangular garden including the path = 4 cm

Calculating the area of path :

» Area of rectanglular path = l × b

where,

  • l denotes the length of the path
  • b denotes the breadth of the path

Substituting the given values :

⇒ Area of path = 16 × 4

⇒ Area of path = 64

  • Area of the path = 64 cm²
