Sketch it !!
x = 3 is halfway between x = 2 and x = 4 so line from vertex R up to PQ is the altitude of the isosceles triangle and is of length 5 - 1 = 4
area = (1/2)((4-2)(4) = 4
x = 3 is halfway between x = 2 and x = 4 so line from vertex R up to PQ is the altitude of the isosceles triangle and is of length 5 - 1 = 4
area = (1/2)((4-2)(4) = 4
