Answer: The area is 45 square inches.

Step-by-step explanation:

so if we know that the the length is 5 times the width then we could represent the length as  5x   and x for the width.  

And we  know the perimeter of the sign so we could set up equation to solve for the side lengths.

The perimeter of a rectangle is  2l + 2w  which means 2 times the length plus two times the width.

2(5x) + 2(x) = 36

10x + 2x = 36

12x = 36

x = 3

Now we know the value of x  so we will plot it into the length and with to find the actually side lengths.

length= 5(3) = 15

width=  3  

Check:  15 + 15 + 3 + 3 = 36  

Now we know the side lengths so to find the area we will have to multiply the length times the width.

3 * 15 = 45
