Sara is working on a geometry problem in her algebra class. the problem requires sara to use the two quadrilaterals below to answer a list of questions. part a: for what one value of x are the perimeters of the quadrilaterals the same? (hint: the perimeter of a quadrilateral is the sum of its sides.) part b: for what one value of x are the areas of the quadrilaterals the same? (hint: the area of a quadrilateral is the product of its base and height.)
