KS2 Primary Maths Age 9-13 - Algebra Quadrilaterals: - Explained

The video tutorial explains how to find the perimeter of a quadrilateral using algebraic expressions. It begins by defining a quadrilateral and the concept of perimeter. The tutorial then demonstrates how to simplify the expression for the perimeter by collecting like terms. Finally, it shows how to solve for the variable X when the perimeter is given as 140 centimeters, resulting in X being 14.6 centimeters.
