We can start by using the formula for the area of a rectangle:
Area = length x width
We know that the width is 9 inches and the area is 135 square inches, so we can solve for the length:
135 = length x 9
length = 135/9
length = 15
So each place mat is 15 inches long.
To find the perimeter (the total length of all the sides), we can use the formula:
Perimeter = 2 x length + 2 x width
Plugging in the values we know, we get:
Perimeter = 2 x 15 + 2 x 9
Perimeter = 30 + 18
Perimeter = 48
So all the sides of the place mat add up to 48 inches.
