Brady made a scale drawing of a rectangular swimming pool on a coordinate grid. the points (-20, 25), (30, 25), (30, -10) and (-20, -10) represent the corners of the pool. what are the dimensions of the pool?

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
