Question

a rectangular park is 45m long and 30m wide .a path 2.5m wide is constructed outside the park .find the area of the path​

Answer 1

Answer:

Area of path=6.5m^2

Area of New park (with path)=1543.75

Step-by-step explanation:

• Length of park=45m
• Width of park= 30m

• Area of park=l*b
• =1350m^2
• Length and width of path =6.25m^2

Therefore,

Area of new park = Area of path +Area of park

=1543.75 m^2

OR

Length of park + width of path* Width of park+ width of path

Hope it will help you

Answer 2

_____________________________

Answer :- 400m²

Step-by-step explanation:

Let ABCD represent the rectangular park and the shaded region represent the path 2.5 m wide.

• To find the area of the path,we need to find (Area of rectangle PQRS-Area of rectangle ABCD) .

We have,

• PQ = (45 + 2.5 + 2.5)m = 50m.
• PS = (30 + 2.5 + 2.5)m = 35m.

Area of the rectangle ABCD =ℓ × Ᏸ = 45 ×30²= 1350² .

1. Area of the rectangle PQRS = ℓ × Ᏸ = 50×35m² = 1750² .

Area of the path = Area of the rectangle PQRS - Area of the rectangle ABCD = (1750 - 1350)² = 400² .
