Answer:
54 minutes
Step-by-step explanation:
We can write a proportion to solve this problem. Put the number of pages over the minutes
27 pages 324 pages
-------------- = ---------------
4.5 minutes x minutes
Using cross products
27 * x = 324 * 4.5
27x = 1458
Divide each side by 27
27x/27 = 1458/27
x =54
Given that the width of the rectangular piccture is:

Where "l" is the length of the picture.
You know that the perimeter is:

The formula for calculating the perimeter of a rectangle is:

Where "l" is the length and "w" is the width.
Therefore, you can substitute the perimeter and the width into the formula, in order to find "l":

Now you can solve for "l":





Hence, the answer is:
Answer:
112+31=143
180-143=37
