Question

A photograph is 3 cm wide and 5 cm long.If the photograph is enlarged so that the long side is 15 cm,how wide will the photograph be?

Answer 1

The width of the photograph is 9 centimetres.

Given data :

Initial length of the photograph is 5 cm

Initial width of the photograph is 3 cm

Increased length of the photograph 15 cm

• Now,we know that a photograph is always enlarged in a multiplication manner.

(Eg. 2×,3×,4× etc)

• At first we have to calculate the enlargement amount by using the following formula

= Increased length / Initial length

= 15/5

= 3 times

• So,the width of the photograph will be also increased for 3 times

• New width of the photograph

= ( Initial length × enlargement amount)

= (3×3)

= 9 cm

The increased with of the photograph is 9 centimetres. (Answer)
