Answer 2

Answer:

Hope this may help u

Step-by-step explanation:

Assuming that the lawn is a perfect rectangle.

L=80m

B=60m

Area of the lawn=L×B

A1=80m×60m

A1=4800 metre square

Now, let's consider the circular swimming pool.

R=7m

Area of the swimming pool=πr^2

A2=π×7m×7m

A2=153.86 metre square

Area of the remaining part of the lawn=Area of lawn-Area of the swimming pool

So,

A=A1-A2

A=(4800-153.86) metre square

A=4646.14 metre square
