Well
we know that the formula for a diagonal is:

so using this we can conclude that the length and the width of this particular square would be 7.071 cm. Hope this helps!
Answer:
* Lucy spent £289.2 on tiles *
Step-by-step explanation:
We know that the tiles are present in a 13 to 2 ratio ( 13 : 2 ) so if there are 16 blue tiles that she buys, the number of red tiles bought should be represented the following -
=
... now this is only assuming that the 13 : 2 ratio is meant by white : blue tiles. Let's solve through cross - multiplication,
13
16 = 2
,
208 = 2
,
= 104 white tiles
So if there are 104 white tiles, and 16 blue tiles, we can determine the total amount Lucy spent on tiles by associating the cost to the type of tile,
£2.80
16 = £44.8,
£2.35
104 = £244.4,
Total Amount Lucy Spent on Tiles = £44.8 + £244.4 = £289.2
