Question

If A is the area of the region bounded by the curve y = `sqrt(3x + 4)`, X-axis and the lines x = -1 and x = 4 and B is that area bounded by curve y² = 3x + 4, X-axis and the lines x = -1 and x = 4, then A : B is equal to ______

विकल्प

• 1 : 2

• None of these

Answer 1

If A is the area of the region bounded by the curve y = `sqrt(3x + 4)`, X-axis and the lines x = -1 and x = 4 and B is that area bounded by curve y² = 3x + 4, X-axis and the lines x = -1 and x = 4, then A : B is equal to 1 : 1.

Explanation:

In both cases, the area will be same.

∴ A : B = 1 : 1
