The diagram shows a scale drawing of a playground. In the scale drawing the playground has a length of 16 cm and a width of 8 cm
kicyunya [14]

Answer:

3 m : 4 cm, 3 m/4 cm, 3 m to 4 cm

Step-by-step explanation:

The actual playground will have an area of 72 m², and have one side be double the other, because the scale drawing does so too.

We can make a system of equations: l * w = 72, l = 2w

Substitute: 2w * w = 72

Simplify: 2 * w² = 72

Divide: w² = 36

Square root: <em>w = 6 m</em> (no negatives due to distances always > 0)

Substitute: l = 2 * 6 m

Simplify: <em>l = 12 m</em>

This means that the relations of one side is <em>6 m : 8 cm</em>. That can be simplified to 3 m : 4 cm.

y=2x+1

x=2y+1

x-1=2y

\frac{x-1}{2} = \frac{2y}{2}

\frac{x-1}{2} = y

\frac{1}{2}x -\frac{1}{2} = y
