Answer:
[tex]630.36\ ft^2[/tex]
Step-by-step explanation:
we know that
To find out the area of the sidewalk, multiply the length by the width of the sidewalk
The width of the sidewalk is equal to
[tex]113.4\ ft-110\ ft=3.4\ ft[/tex]
or
[tex]75.4\ ft-72\ ft=3.4\ ft[/tex]
The area is equal to
[tex]113.4(3.4)+72(3.4)\\385.56+244.8\\630.36\ ft^2[/tex]
