Question

EXERCISE
1. A rectangular park is 35 m long and 20 m wide. A path 2 m wide is constructed outside the pat
Find the area of the path.
2. 5 m wide path is built inside a rectangular field of size 550 m × 360 m. Find the area of the path​

Answer 1

Answer:

Step-by-step explanation:

∴Area of the path =total area of the field-remaining area

Total area of the field=550x360

                                =198000m²

Remaining area=540x350

                        =189000m²

∴Area of the path=9000m²

Answer 2

Answer:

Here is your answer :-

Step-by-step explanation:

1)length of park = 35m

breadth of part = 20 m

(inner) area = l×b = 35×20 = 700 m^2

Now, a path 2m wide is constructed outside the park

so, new length = 35 +2 +2 = 39m

new breadth = 20 +2 +2 = 24m

new (outer) area = l×b = 39×24 = 936m^2

=> area of path = outer area - inner area

= 936 - 700 = 236m^2

2) (outer) area = 550×360 = 1,98,000m^2

Now, a path 5m wide is constructed inside the field.

new length = 550 - 5 - 5 = 540m

new breadth = 360 - 5 - 5 = 350m

new (inner) area = 560×370 = 1,89,000m^2

=> area of park = outer area - inner area

= 1,98,000 - 1,89,000

= 9000m^2
