Answer 2

Hey!

Measurement of tiles

Length = 20cm

Breadth = 40cm

Measurement of prayer hall

Length = 16m = 1600cm

Breadth =9 m = 900cm

Area of tiles = length × breadth

= (20 × 40) cm^2

Area of prayer hall = length × breadth

= (1600 × 900) cm^2

Required Tiles = Area of prayer hall / Area of tiles

= (1600 × 900) / (20 × 40)

= 1800 tiles

(c) 1800

Hope this helps ✌✌
