Question

A sidewalk with exterior dimensions 5xy units by 3xy units surrounds a rectangular pool at the town park. The pool is 2xy units wide and xy units long. Write an expression to find the area of the sidewalk. Then find the area

Answer 1

Here! :]

Explanation:

Area of sidewalk = Area of the cover area of sidewalk minus area of pool

Area of sidewalk = ((5xy)*(3xy)) - ((2xy)*(xy))

Continue to solve

`15x^(2) y^(2)` -
`2x^(2) y^(2)` =
`13x^(2) y^(2)`

Area of sidewalk =
`13x^(2) y^(2)`
