Answer:
Length = 50 units
width = 35 units
Step-by-step explanation:
Let A, B, C and D be the corner of the pools.
Given:
The points of the corners are.
We need to find the dimension of the pools.
Solution:
Using distance formula of the two points.
----------(1)
For point AB
Substitute points A(30, 25) and B(30, 25) in above equation.
AB = 50 units
Similarly for point BC
Substitute points B(-20, 25) and C(30, -10) in equation 1.
BC = 35 units
Similarly for point DC
Substitute points D(-20, -10) and C(30, -10) in equation 1.
DC = 50 units
Similarly for segment AD
Substitute points A(-20, 25) and D(-20, -10) in equation 1.
AD = 35 units
Therefore, the dimension of the rectangular swimming pool are.
Length = 50 units
width = 35 units
