Tonne is a metric unit equal to 1000 kilograms.
Answer and explanation:
Surface area of a rectangle = length * width
Surface area of a square = a² where a is length of a side
To find total surface area of the the five pieces of paper, we add up all the areas of all the shapes
Given that length of rectangle =3.5
And width = 2
Area of rectangle =3.5*2=7
Area of 3 rectangles given they are all equal = 7*3=21
Since width of rectangle equal to width of square and all sides of square are equal
Area of square = 2 *2 =4
Area of the two squares =4*2=8
Total surface area of the five plane shapes = 21+8= 29
The slope is -1/2x in this case because it is always next to a variable y=mx+b.
Let Tamara invests amount 
in 3% account. She invests 
in 2% account.
The interest after t years is given by
. After 1 year the two interests are equal, that is
Thus, Tamara has to invest 
in 3% account and 
in 2% account.
