Q # 17. please help me with this

Answer 1

Hi there!

Dimensions of rectangular room :-

• Length = 109 inches
• Breadth = 103 inches

Dimensions of square tiles :-

• Each side = 3 inches

It's known :-

No. of tiles = Area of rectangular room / Area of tile

No. of tiles =
`\frac {109 × 103}{3}`

No. of tiles =
`\frac {11227}{9}`

No. of tiles = 1,247

Hence,
Th' number of tiles required for the job is 1,247

~ Hope it helps!
