A photocopier increased the sides of a square in the ratio 4:5.
Svetach [21]

Answer:

The sides are increased by a percentage of 25%

Step-by-step explanation:

Let

x -----> the length side of the original square

y ----> the length side of the increased square

we have

\frac{x}{y} =\frac{4}{5}

y=\frac{5}{4}x

y=1.25x

the increase is calculated by subtracting x from y

so

y-x=1.25x-x=0.25x

Remember that

0.25=\frac{25}{100}=25\%

therefore

The sides are increased by a percentage of 25%
