Area of a rectangle is 2400 sq.cm. If length and breadth are in the ratio 8 : 3, find length and breadth? If length and breadth are increased by 20 cm, then find the ratio between length and breadth |
|
Answer» Length = 8x Breadth = 3x \(8x\times3x=2400,\) \(24x^2=2400\) \(x^2=\frac{2400}{24}=100;\) \(x^2=\sqrt{100}=10\) length = 8 × 10 = 80, Breadth = 3 × 10 = 30 When length and breadth are increased by 20, then length = 100; Breadth = 50 length : breadth = 2 : 1 |
