Pierce is making a rectangular frame for a photo collage that had a perimeter of 72.2 inches. The length of the frame is 20.3 inches and width of the frame is x inches. Write an equation that could be used to find width or the frame

72.2 = 2x + 40.6

Step-by-step explanation:

Formula for perimeter of a rectangle = 2( width + lenght)

P = 2 ( w + l)

P= 2w + 2l    (i)

We have been given that width = x

and lenght = 20.3 inches and P = 72.2 inches

We substitute the values of P, w and l into equation (i)

72.2 = 2x + (2*20.3)

72.2 = 2x + 40.6
