In geometry, transformation involves changing the position and/or size of a shape.
<em>The transformation that will change the size of ABCD is dilation.</em>
There are four transformations in geometry:
- Translation
- Reflection
- Rotation
- Dilation
Of all types of transformation, dilation will change the size of the shape,
The new shape will either be enlarged or reduced
<em>Either ways, the size of the shape will be altered.</em>
<em>When the size is altered, the perimeter will not remain the same.</em>
<em />
Hence. dilation will change the perimeter of ABCD.

Here is the solution...
This is a proportional relationship.
A proportional relationship is nothing the two quantities vary directly with each other.
The proportional equation<em> y = k x</em>. where k is the constant proportionality.
This means that as <em>x</em> increases, <em>y </em>increases and as <em>x</em> decreases, <em>y</em> decreases.
Here we use the proportional relationship to find the equation.
The number of miles driven is proportional to the number of gallons of gas.
Therefore, the equation is Miles = k Gallons
That is <em>M = k G, </em>where k represents the number of miles driven per gallon of gas.
A vendor is selling championship t-shirts for $33.00. After a day, sales were so good, they raised the selling price by 25%. The amount of percent increase on the t-shirts is $41.25
The selling price is the price at which a good is being sold to a customer.
Given that:
- The vendor sells championship t-shirts for = $33.00
- After a day the selling price increased by 25%
The amount of the percent increase on the t-shirts after a day can be estimated as:
= $8.25
Now, after a day, the vendor sold the cloth at the rate of:
= $33.00 + $8.25
= $41.25
Therefore, we can conclude that after a day, the t-shirts is being sold for $41.25 after raising the percentage by 25%.
