Answer:
(in step-by-step explanation)
Step-by-step explanation:
The ratio x:y is the same as the fraction x/y if that helps, so it is basically putting the coordinates into a fraction. Here is a video that might help also: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-ratios-prop-topic/cc-6th-ratio-word-problems/v/ratios-on-coordinate-plane
Coordinate planes are a way of expressing data, so if it makes it easier, put the data into a ratio! Sorry, it is a bit difficult to explain such a broad question.
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
