and say how did you do it
i will mark you the brainlist

5 plus 15 is 20 and then subtract 10 it will become 10 then add 20 it became 30 then subtract 15 it will become 15 then add 25 to 15 answer 40

Step-by-step explanation:

the numbers are repeated again and again like we added 5 to 15 we got 20

then later we added 20 to 10 it became 30

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
