Question 1051919
Each side is {{{2x+1}}}. There are 4 of these sides that are the same length. So we multiply that side length by 4 and set it equal to the perimeter of 28


{{{4*(2x+1) = 28}}}


Let's solve this equation for x


{{{4*(2x+1) = 28}}}


{{{8x+4 = 28}}}


{{{8x+4-4 = 28-4}}}


{{{8x = 24}}}


{{{8x/8 = 24/8}}}


{{{x = 3}}}


Now we use the fact that x = 3 to find the side length 


{{{2x+1 = 2*3+1 = 6+1 = 7}}}


So each side length of this square is 7 inches. You can simply divide 28 over 4 to see this


28/4 = 7


Your teacher will most likely want you to solve for x first though.
