Question

the floor of room 7.5m long and 5 m broad is to be tiled. how many tiles will be require this job if each square tile to be used was side of 50 cm?​

Answer 1

Answer:

150 tiles

Step-by-step explanation:

• length of the floor = 7.5m
• breadth of the floor = 5m
• squared shaped to be tiled side =50 cm

Solution

Area of foor = Length xBreadth

$7.5 \times 5 = 37.5 {m}^{2} = \\ 37.5 \times 100 \times 100 = 375000 {cm}^{2} \\ now \: area \: of \: tiles \: side \: 50cm \\ {a}^{2} = 50 \times 50 = 2500 {cm}^{2} \\ time \: required = \frac{375000}{2500} = 150tiles$
