Part 2) The perimeter is
Step-by-step explanation:
Part 1) Determine both dimensions
Let
x-----> the length of the pool
y----> the wide of the pool
we know that
The area of the rectangle (pool) is equal to
we have
so
-----> equation A
----> equation B
substitute equation B in equation A and solve for y
using a graphing tool to solve the quadratic equation
the solution is
see the attached figure
Find the value of x
------>
Part 2) Find the perimeter
The perimeter of rectangle (pool) is equal to
we have
substitute
Answer:
The answer is 8/25. This is because 32% is equal to 32/100, when you simplify this it equals 8/25.
40/50*100=80%
Abby reach 80% of her goal
