Question

Rectangular floor measurements: 

Length= 9m

Width= 4.5

 

'Toji is going to cover the floor with floor boards.

Each floor board is 0.1 wide, and 1.5m long.

 

Work out the smallest number of floor boards Toji needs.'

 

Thank you in advance.

Answer 1

If the length of the floor is 9m and each board is 1.5m long then you need 9/1.5 or 6 board lengths to cover the length of the floor.

 

Similarly, if the width of the floor is 4.5 and the boards are 0.1 wide, then you need 4.5/0.1 or 45 board widths to cover the width of the floor.

 

45 x 6 = 270 boards

 

Alternatively,

#boards needed is given by (9 * 4.5)/(1.5 * 0.1) = 270 boards.

 

Hope this helps.
