Answer 1

The length is 250 meters

Explanation:

If we look at the left corner of the diagram we see a scale. According to the scale factor of the map

1 cm :1000 cm

The length of the lap on the map is 25 cm

So (25 × 1000) = 25000 cm

Since

1 meter = 100 centimeter

So the actual length of the lap = 25000 ÷ 100 = 250 meters

Answer 2

250 meters

Explanation:

We are given the picture of a reservoir which is made using the scale 1 : 1000.

We are to find the actual length of the lap if one lap along the perimeter of the reservoir is 25 cm.

Using the ratio method:

`(1)/(25):(1000)/(x)`

`x=25000 cm`

Converting it from centimeter to meter:

`(1m)/(x)= (100cm)/(25000cm)`

`x=(25000cm)/(100cm)`

`x=250m`

Therefore, the actual length of the lap is 250 meters.
