three sides of quadrilateral are the same length,g q. The length of the fourth side is 7 inches. The perimeter of the quadrilateral is 40 inches. write and equation that represents the situation.

The situation can be represented using the equation 3g + 7 = 40How to determine the equation that represents the situation?From the question, we have the following parameters that can be used in our computation:Length of three sides = gLength of the fourth side = 7Perimeter = 40The perimeter of a quadrilateral is the sum of the sides of the shapeThis means thatP = sum of the 4 sidesSo, we haveP = g + g + g + 7EvaluateP = 3g + 7Rewrite as3g + 7 = 40Hence. the equation that represents the situation is 3g + 7 = 40Read more about perimeter athttps://brainly.com/question/24571594#SPJ1
