The coordinate plane shows the floor plan for a swimming pool. What is the area of the pool’s border?"

emmasim [6.3K]

A = Area
L= Length = 15
W + widith = 10
A = 150
The pool area is L = 10
w= 5
A= 50
So the area of the perimeter = 100 square meters

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Boat A(3.1, -1)

Boat B(-4.1, -1)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(-4.1-3.1)^2+(-1+1)^2}$
Subtract/Add: $d = \sqrt{(-7.2)^2+(0)^2}$
Exponents: $d = \sqrt{51.84}$
Evaluate: $d = 7.2$

Answer:

365 and 1/2 blocks will be used

The scale fact is 0.25

Step-by-step explanation:

So . .

We create a ratio 1:2

This represents 1 block is equivalent to 2 feet

Simply 1450 ÷ 2 = 725

So . . There are 725 feet and because One block is equal to 2 feet you divide 725 ÷ 2 = 362.5 blocks will be used

To find the scale factor simply divide the deminsions of the new shape by old

362.5 ÷ 1450 = .25
