Erin created a scale drawing for a garden that will be 10 ft by 5 ft. She plans to include a section in the garden for herbs, wh
Elanso [62]

Answer:

The dimensions of the herb garden in the scale drawing are 2.4 in. by 6 in

Step-by-step explanation:

we know that

The dimensions of the garden in the actual are 10 ft by 5 ft

The dimensions of the garden on the scale drawing are 12 in. by 6 in

step 1

Find the scale factor

To find the scale factor divide the corresponding side on the scale drawing by the corresponding side in the actual

so

\frac{12}{10}\ \frac{in}{ft}

simplify

1.2\ \frac{in}{ft}

That means

1.2 inches in the drawing represent 1 foot in the actual

step 2

Find out  the dimensions of the herb garden on the scale drawing

we know that

The dimensions of the herb garden in the actual are 2 ft by 5 ft

Multiply by the scale factor

so

2\ ft=2(1.2)=2.4\ in

5\ ft=5(1.2)=6\ in

therefore

The dimensions of the herb garden in the scale drawing are 2.4 in. by 6 in

  • Increase rate is 6% per year = 1.06 times

<u>The model of the growth is:</u>
