Answer: 
Step-by-step explanation:
The perimeter of a rectangle can be calcualated with this formula:

Where "l" is the lenght and "h" is the height.
The area of a rectangle can be found with this formula:

Where "l" is the lenght and "h" is the height.
In this case we know that:

Therfore, we can susbsitute them into
and solve for "h" in order to find its value:

Find two number whose sum is 3 and whose product is -40. These are -5 and 8. Then, factorizing, we get:

The positive value is the height. Then:

Since the length is 3 centimeters greater than its height, we get that this is: Then:

Substituting values into
, we get that the perimeter is:

3:30
Half past means 30 min after

Answer:
1/2
Step-by-step explanation:
u need to use those red dots
with the dot at the bottom you go 1 square to the right
and then you go 2 squares up
and ur answer is 1/2 and you might want to use rise over run = rise/run
After solving for w using inverse operations, w would have to equal 5.74 to make this equation true.
