Question

Find the equation and solve it.

Answer 1

4(3x + 1)= 76
*There are 4 sides to a square and they are all equal in length, so you would mulitply 3x +1 by 4
*The total perimeter is 76
*Distribute the 4 into the equation

12x + 4=76
*subtract 4 on both sides

12x=72
*divide 12 on both sides

x=6
*Plug 6 in for x in the equation

3(6) +1
*this means that each side of the square would be 19 meters
*If you want to check to make sure you solved for x correctly, just plug it into the equation[4(3x + 1)]

Hope this helps!
