The actual length of a painting was 2 m. What is its length in the photograph if the scale used is 1 mm : 20 cm.

योग

उत्तर

The actual length of the painting was 2 m or 2 × 100 = 200 cm  ...[∵ 1 m = 100 cm]

Scale used in the painting = 1 mm : 20 cm

Hence, length of painting in photograph = Scale × Actual size  ...`[∵ "Scale" = "Size drawn"/"Actual size"]` 

= `1/20 xx 200`

= 10 mm
