Draw parallelogram ABCD with the following measurements and calculate its area.
AC = 8 cm, BD = 6 cm and ∠COD = 90° where and
intersect at ‘O’.
Given. ABCD is a parallelogram.
AC = 8 cm, BD = 6 cm
∠COD = 90°
Formula used. Area of parallelogram = base × height
Steps of construction
Step 1 : Draw line segment AC of 8cm
Step 2 : Mark O as midpoint of AC
Step 3 : Draw line B’D’ through O which makes ∠COD’ = 120°
Step 4 : Make Arcs of 3cm form O on both sides of B’D’
Step 5 : Join AB;BC;CD;DA
Step 6 : Draw a perpendicular on AB from point D and name the intersection point as E
Area of parallelogram = base × height
= AB × DE
= 5cm × 4.8cm
= 24cm2
Conclusion. Hence; parallelogram ABCD is constructed and its area
is 24cm2
