yaroslaw [1]
To divide fraction by number we can multiply fraction by inverse of number.
Lets find inverse
21=\frac{21}{1} =====> \frac{1}{21} - its inverse of 21
Now we can multiply it
\frac{9}{49}* \frac{1}{21}= \frac{9*1}{49*21} = \frac{9}{1029}= \frac{9:3}{1029}= \frac{3}{343} - its our result

The perimeter of a rectangular parking lot is 320 m.
Nezavi [6.7K]

Answer:

63 metres

Step-by-step explanation:

A rectangle has 4 sides

2 of these sides are the lengths

The other 2 sides are the width

If the length of one side is 97 metres, the other side length must also be 97 metres

The two lengths then add together (97 + 97) to become 194 metres

Now we can use this information to calculate the width

320 (the total perimeter) subtract 194 (The total length) = 126 metres

This means that 126 metres is the total width

Because there are two sides which add up to the total width we divide 126 by 2

This allows us to get the measurement of the width

126 divided by 2 = 63 metres
