Answer 1

Answer:

Length of the path =45mwidth of the path =2.5marea of path(rectangle)= l×b=45×2.5=112.5

Step-by-step explanation:

Answer 2

Answer:

• Area of park = 350 m²

Step-by-step explanation:

Given:

• Outer length of rectangle = 45 m
• Outer breadth of rectangle = 30 m
• Inner length of rectangle = 45 - 2.5 - 2.5 = 45 - 5 = 40 m
• Inner breadth of rectangle = 30 - 2.5 - 2.5 = 30 - 5 = 25 m

To Find:

• Area of park

Now, Area of park = Outer area - Inner area

⇒ Outer area of park = 45 × 30

⇒ Outer area of park = 1350 m²

⇒ Inner area of park = 40 × 25

⇒ Inner area of park = 1000 m²

⇒ Area of park = Outer area - Inner area

⇒ Area of park = 1350 m² - 1000 m²

⇒ Area of park = 350 m²

Hence, Area of park = 350 m².
