Answer:

(3x+3y+9)\ ft^{2}

Step-by-step explanation:

Let

x------> the length of the original play space

y-----> the width of the original play space

we know that

The area of the original play space is equal to

A=xy

The area of the new play space is equal to

An=(x+3)(y+3)\\An=xy+3x+3y+9

Find the difference

An-A=(xy+3x+3y+9)-(xy)\\An-A= (3x+3y+9)\ ft^{2}
