If each side of a rhombus is doubled, how much will its area increase?
विकल्प
1.5 times
2 times
3 times
4 times
उत्तर
2 times
Explanation:
Let b be the side and h be the height of a rhombus.
∴ Area of rhombus = b × h ......[∵ area of rhombus = base × corresponding height]
If each side of rhombus is doubled, then side of rhombus = 2b
Now, area of rhombus = 2b × h = 2(b × h) = 2 times of original
Hence, the area of rhombus will be increased by 2 times.
