Answer 1

Answer:

The length of all sides of place mat is 48 inches.

Step-by-step 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

$\frac{9x}{9}=\frac{135}{9}\\x = 15$

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.

Answer 2

Answer:

45

tbh i don't really know. I've seen people say that it's 45, others have said 48. I don't see how either of them make sense. Maybe i'm doing the math wrong I don't know. I think it's 45
