please help

Answer 1

`630.36\ ft^2`

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

`113.4\ ft-110\ ft=3.4\ ft`

or

`75.4\ ft-72\ ft=3.4\ ft`

The area is equal to

`113.4(3.4)+72(3.4)\\385.56+244.8\\630.36\ ft^2`
