Answer 1

Answer:

112m

Step-by-step explanation:

Answer 2

Step-by-step explanation:

We have,

Length of rectangular plot=80m.

Breadth of rectangular plot=60m.

Now,

Area =Length×breadth

Area=80×60=4800m

2

If the path is all round the rectangular plot.

Then It’s length and breadth will increase.

So, the length of path

=80+1.5+1.5

=80+3

=83m.

Breadth of the path

60+1.5+1.5

=63m.

Area of the rectangular plot along with the path=l×b

Area=83×63

=5229m

2

Therefore, Required area

=5229−4800

=429m

2

Hence, this is the answer.
