    • Question

      In parallelogram ABCD, point E is located on side AB,

      and line segment DE is drawn perpendicular to AB. Given that AD measures 5 cm, AB is 12 cm, and AE is 3 cm, determine the area of the parallelogram.
      A 44 cm² Correct Answer Incorrect Answer
      B 52 cm² Correct Answer Incorrect Answer
      C 60 cm² Correct Answer Incorrect Answer
      D 48 cm² Correct Answer Incorrect Answer

      Solution

      Image Since DE is perpendicular to AB, AED forms a right angled triangle whose hypotenuse is AD. Using Pythagoras theorem in triangle AED, So, ED2 = AD2 – AE2 = 52 – 3= 25 – 9 = 16 So, ED = √16 = 4 cm Area of a parallelogram = base × height = AB × ED = 12 × 4 = 48 cm2
