The length of a rectangle is 5 inches shorter than the width. What is the width of the rectangle if the perimeter is 48 inches? Please show the equation

Respuesta :

Perimeter = 2L + 2W  = 48                    WHERE L=length and W=width

The length must be longer than the width so im going to say that L = W + 5

so the equation is 

2(W + 5)  + 2W = 48

2W + 2W + 10 = 48

4W = 38 

W = 38/4 = 9.5 ins and  

length = 5+9.5 = 14.5 ins
