Question

ABCDis a parallelogram. AB=8cm, AD=4cm,<B=120°
a) What is <A
b) What is the perpendicular dustance from D to AB
c) What is the area of ABCD
​

Answer 1

We know that, Area of a parallelogram = Base × Corresponding altitude

We know that, Area of a parallelogram = Base × Corresponding altitude ∴ Area of parallelogram ABCD = AD × BN = AB × DM ⇒ AD × 5 = 8 × 4

We know that, Area of a parallelogram = Base × Corresponding altitude ∴ Area of parallelogram ABCD = AD × BN = AB × DM ⇒ AD × 5 = 8 × 4 ⇒ AD = 8× 4/58

We know that, Area of a parallelogram = Base × Corresponding altitude ∴ Area of parallelogram ABCD = AD × BN = AB × DM ⇒ AD × 5 = 8 × 4 ⇒ AD = 8× 4/58 =6.4cm
