Alfie wants to buy a computer. The price of a basic computer is £400 The price of a better computer is £490 Alfie thinks that the better computer will cost him 20% more than the basic computer. Show whether or not he is correct.

He is not correct

Step-by-step explanation:

Well to determine whether he is correct find 20% of the basic computer computer and add it to its price to determine if it equals 490 euros

20% * 400 = 80

Now add 80 to 400 to see if it equals 490

400 + 80 = 480

480 ≠ 490  

He is wrong

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
