Question

A rectangular park is 35 metre long and 20 metre wide . A path 2m wide is constructed outside the park. find the area of the path
answer please and neat ​​

Answer 1

Answer:

Step by step explanation:

There will be two rectangles inside and outside.

Total area (inside) = l×b

= 35×20 units

= 700m²

new sides= 35+2+2 (2 sides) and 20+4

= 39m and 24m

total area (outside) = 39×24 units

= 936m²

area of path = area of inner rectangle - area of outer rectangle.

= 936-700m²

= 236m²

hope it helped

Answer 2

Answer:

Step-by-step explanation:

l=35m

b=20m

A path of 2m wide is constructed

Then outside dimensions of the rectangular park are

l=35+4=39m

b=20+4=24m

The area of the path = the area of outside rectangle - the area of inside rectangle

=l*b - l*b

=39*24 - 35*20

= 936 - 700

=236m^2

Therefore area of the path of the rectangular park is 236m^2
