Question

Erica is tiling the floor of a rectangular room of length 3 meters and width 2.5 meters. She uses square tiles of side 25 centimeters.
Calculate

a) how many tiles will fit along the length of the room
b) how many tiles she will need altogether

Answer 1

Answer:

A)12 B) 12+9= 21

Step-by-step explanation:

First we will see that how many 25 centimetres are there in 3 metres for the answer of question 'A' as we know that there are 100 centimetres in 1 metre then 300 centimetres in 3 metres ad if 300 is divided by 25 answer is 12.

Then 'B' is a bit tricky as after fitting the tiles along the length it will even occupy 25 centimetres of width, so we will subtract 25 centimetres from 250 centimetres (2.5 metres) and the answer is 225 and when we divide it with 25 we get the answer as 9, so 'B' is asking the total no. of tiles then 12+9= 21 (Final answer)

Hope it helped you!!
