The floor of the hall is to be tiled fulller size. Find the number of tiles required.7. The dimensions of the floor of a rectangular hall are 4 m x 3 m.8 cm × 6 cm rectangular tiles without breaking tiles

Answer»

Dimensions of floor of Reactangular hall are length l = 4m = 400 cmbreadth b = 3m = 300 cm

Dimension of tileslength l1 = 8 cm, breadth b1 = 6 cm

Let number of tiles required = n

Then, n*Area of tile = Area of floor n*(l1*b1) = l*bn = 400*300/8*6n = 50*50n = 2500

Therefore number of tiles required = 2500
