प्रश्न
If the base and height of a parallelogram are in the ratio 7 : 3 and the height is 45 cm, then fixed the area of the parallelogram
उत्तर
Given: Base, Height = 7 : 3
Let base = 7x cm
Height = 3x cm
Also given height = 45 cm
3x = 45 cm
x = `45/3` = 15
Now base = 7x cm
= 7 × 15 cm
= 105 cm
Area of the parallelogram = b × h sq.unit
= 105 × 45
= 4725 cm2
