Question

how many tiles will be required to cover a floor of area x²+3x+2m² completely. if area of each tile is is x+1​

Answer 1

If the area bounded by the curve y=f(x), x-axis and y-axis be a square units then area bounded by f(∣x∣) and x-axis be twice of a

Shaded Area =∫01f(x)dx=65sq.units

again Graph of f(∣x∣)

∴ Required Area bounded by f(∣x∣)

=∫−11f(x)dx=2∫01f(x)dx=2.65=35sq units
