There are 52 weeks in a year.
Using 50 for the number of weeks in a year is a(n) round.
Rounding is a process which we approximate the known number by just scaling it up or down.
In rounding the numbers less than 5 are scaled to one number less than the given integer and numbers such as 5 or above than 5 are scaled a number greater than the given number .
For example if there were 55 or more than weeks in a year we can say there are approximately 60 weeks in a year.
But there are 52 weeks so we <u><em>round</em></u> it to 50 weeks as 2 is less than 5.

Answer:
Step-by-step explanation:
we know that
The area of the backyard pool to be resurfaced is equal to the area of the base plus the area of its four lateral sides.
so
where
B is the area of the base
P is the perimeter of the base
H is the depth of the pool
<em>Find the area of the base B</em>
substitute the given values
<em>Find the perimeter of the base P</em>
substitute the given values
we have
<em>Find the area of the backyard pool to be resurfaced</em>
substitute the values
Well we know that sin(angle) = opposite/hypotenuse. using the angle of 38 degrees we see that the opposite is 24 and the hypotenuse is x. So we fill in equation:
sin (38) = 24/x
x *sin (38) = 24
x = 24/ sin (38)
x = 38.98
x = 39.0
