Answer:
Part a) The draw in the attached figure
Part b) The length of the playground is and the width of the playground is
Step-by-step explanation:
I assume that the playground has a rectangular form
Let
x-----> the length of the playground
y ----> the width of the playground
we know that
The area of the playground is equal to
so
-----> equation A
-----> equation B
substitute equation B in equation A
using a graphing calculator ------> solve the quadratic equation
The solution is
Find the value of y
therefore
The draw in the attached figure
The length of the playground is
The width of the playground is
You should mulitply. $23.78 * 0.20 = 4.756
Then you add. 4.756 to $23.78 = $28.536
Now you round $28.536 to the hundredths so that you can pay it with coins.
The anwser is $4.76 and the total amount for the taxi ride would be $28.54
