Answer:
The length of all sides of place mat is 48 inches.
Explanation:
Given that:
Area of place mat = 135 square inches
Width of place mat = 9 inches
Length of place mat = x
Area = Length * Width
135 = 9x
For length of all sides, we will find the perimeter.
Perimeter = 2(Length + Width)
Perimeter = 2(15+9)
Perimeter = 2(24) = 48 inches
Hence,
The length of all sides of place mat is 48 inches.
