1. If a soccer lover has a photo frame that is 180mm in length and 125mm in breadth with a scale factor of 4 .Calculate the dimension of enlargement.

2. If he wanted to reduce the photo frame with area equal to 9cm squared. find the scale factor.

The scale factor was 2:1, or 200%

A Scale Manager kit comprises of the following:

*Please Note:* Ensure antennae cables do not come into contact with each other

The antennae coils require a minimum gap between them of 50mm - 2?. It is also necessary that the coils are at least 40mm -1½" from elbows and junctions.

- One computerised electronic water descaler
- One 12 volt power supply, cable length 1.8m - 6?

Optional when ordering, 5m - 16½' power supply extension lead - Antenna cable with red plug
- Antenna cable with
**black**plug - Five plastic cable ties (1 spare)
- One attachable
**black**antenna plug - One attachable red antenna plug

- The gap between the coils must be in excess of 60mm - 2½" no upper limit
- Coils require a minimum of 50mm - 2? each side of uninterrupted straight pipe
- Direction of coils is essential - see over
- Ideally a 125mm + (5?+) straight run of pipe is required for each antenna coil
- Direction of Water Flow is immaterial
- Connect red plugs to red sockets and black to black
- Scale Manager is effective on all pipes (copper, plastic, lead, steel etc)
- Performance is not impaired if the pipe is painted
- The Control Unit can be fitted at any angle or plane
- A 13-amp socket is required for the power supply

The antennae coils require a minimum gap between them of 50mm - 2?. It is also necessary that the coils are at least 40mm -1½" from elbows and junctions.

I believe factors can be calculated on any basic calculator.

Starting with 1, increasing by 1 until you get to square root (number) + 1

Let's do an example.

28

square root (28)+1 = 6

Factors

1, 28/1=28

2, 28/2=14 14*2 - 28 = 0 (when you divide, you get no decimal)

3, 28/3=9.33333 - not a factor - doesn't go in evenly

4, 28/4 =7

5, 28/5=5.6 - not a factor - doesn't go in evenly

6, 28/6=4.66666 - not a factor

So now we can list our factors - 1, 28, 2, 14, 4, 7

Putting them in order, we get 1, 2, 4, 7, 14 and 28.

Good luck,

Paul

Find the scaling ratio

Perimeter of first pentagon is 12*5=60 cm

Scale factor (2nd/first)=140/60 =7/3

**Ratio of areas varies as the square of the scale factor for the lengths**

Area of second / area of first =(7/3)^2 =49/9

Area of second pentagon =**248 *(49/9) cm^2**

Finish the calculation.

The two pentagons are similar. If k is the scale factor for the lengths, the ratio of the areas is k^2.

Pent 1 side =12 cm

Pent 2 side =140/5 =28 cm

Scale factor (larger over smaller) is k=28/12=7/3

Area of Pent_2= (49/9)*Area of Pent_1

Your answer should be C.

Pent 1 side =12 cm

Pent 2 side =140/5 =28 cm

Scale factor (larger over smaller) is k=28/12=7/3

Area of Pent_2= (49/9)*Area of Pent_1

Your answer should be C.

The figure are similar, corresponding sides are proprtional

L1/L'1=L2/L'2= ... =k , the scale factor for lengths.

However, if scale factor for lengths is k, the ratio of area is k^2 find

**Scale factor**

Use the given area to find the proportionality factor then use it the ratio of length to find the missing distance between the parallel sides.

Area of new /Area of old=360/250=36/25=k^2

k=SQRT(36/25)=6/5

**Ratio of lengths =k=6/5**

Distance between parallel sides of new patio/Distance between parallel sides of old patio=6/5

Distance between parallel sides of new patio= (6/5)*12.5=15

**The distance between the parallel sides of the new patio is 15 feet.**

Use a ruler to measure the lengths of the sides and a protractor to measure the angles. The scale factor is the lengths of one divided by the lengths of the other.
