The area of a square is the product of the length of each side with itself, i.e. Area A = s x s where s is the length of each side of the square.
Mr. Jenson wants to tile 3.6 sq. meters or 36000 sq. cm.
Total number of tiles is 250.
Area of tile = = 36000/ 250 = 144 sq. cm
s X s = 144 sq. cm

<u>Answer:</u>
The amount lost over the 3 years s 2567.25£
<u>Explanation:</u>
where F = final value after n years
I = initial value of the car in 2017 = £18000 (given)
Since the value is depreciated 5% every year for 3 years,
r = percentage rate of depreciation = 5% (given)
n = 3 years
Substituting these values in formula, we get
=
