Question

How many tiles will be require to cover a floor
of area (x2 + 3x + 2) m2 completely If the area of each tile is (x + 1) m^2?​

Answer 1

Step-by-step explanation:

no. of tiles = ar. of floor/ar. of one tile

= (x²+3x+2)/x+1

= (x²+x+2x+2)/x+1

= {x(x+1)+2(x+1)}/x+1

= (x+2)(x+1)/(x+1)

= x+2

hence fhe no. of tiles is (x+2)
