A graphic artist is designing a poster that consists of a rectangular print with a uniform border. The print is to be twice as tall as it is wide, and the border is to be 3 in. wide. If the area of the poster is to be 680 in. square, find the dimensions of the print.

1. You are asked to find the width and height of the print. A border is 3 in. wide surrounds the print. Draw a diagram

A graphic artist is designing a poster that consists of a rectangular print with a uniform border. The print is to be twice as tall as it is wide, and the border is to be 3 in. wide. If the area of the poster is to be 680 in. square, find the dimensions of the print.

2. Let w = width of the print. Then 2w=height of the print. Since the dimensions of the poster are 6in. Greater than the dimensions of the print, w+6 = width of poster and 2w+6= height of poster. Label your diagram
