A wire is first bent into the shape of a rectangle with width

4in and length 14in. Then the wire is unbent and reshaped into a square. What is the length of a side of the square?

First you have to find the area of the wire

Area of a rectangle=L*W = 14*4=56

Then divide that by 4 since a square has 4 equal sides

56/4=14

The length of a side of a square is 14 in

First find the perimeter of the rectangle: 2w+2l which is 8+28=36. Then find the square root of 36 which is 6 so that is the answer.
