PLEASE HELP ME FAST!!!

Answer 1

1. A is area, s is side, w is width
2. A = 104 in²
3. $3,600

Explanation:

For #2:

`A = 15^(2) - (15 - 2(2))^(2)\\A = 225 - (15 - 4)^(2)\\A = 225 - 11^(2)\\A = 225 - 121\\A = 104`

For #3:

`A = 18^(2) - (18 - 2(3))^(2)\\A = 324 - (18 - 6)^2\\A = 324 - 12^2\\A = 324 - 144\\A = 180`

Then the price would be 180 in² × 20 = $3,600.
