LenaWriter [7]

Answer:

The area of the actual playground is $54\ yd^{2}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

let

z------> the scale factor

x------> the area of the actual playground

y-----> the area of the scale model of a playground

$z^{2}=\frac{x}{y}$

we have

$z=3$

$y=6\ yd^{2}$

substitute and solve for x

$3^{2}=\frac{x}{6}$

$x=9*6=54\ yd^{2}$
