Step-by-step explanation:
The area of a rectangle is 171 m²
Let l is the length and b is the width of the rectangle
It width is 10 m less than the length. So,
b = l-10 ...(1)
Area of a rectangle is given by :

or
l = 9 m or l = 19 m
If l = 9 m,
b = 9-10 = -1 m (can't be possible)
If l = 19 m
b = 19-10 = 9 m
So, the length an the breadth of the rectangle is 19 m and 9 m respectively.
One decimal place means one place after the decimal point, therefore you should round appropriately to get to one place after the decimal point.
The answer would therefore be 12.6 <span />

Answer:

Step-by-step explanation:

When converting mixed numbers (such as the one above), to improper fractions, we must first multiply the whole number by the denominator:

Then, add the numerator the the product:

Now, put the sum over the denominator to get your solution:

-
To check your work, you can convert the improper fraction to a mixed number to make sure you will end up with
.
Divide
into
:
with a remainder of 
Put the remainder over the denominator:

Therefore, our solution is correct!
