Explanation of Solution
Given Information: A figure showing two similar quadrilaterals
Formula used:
When two quadrilaterals are similar the ratio of lengths of their corresponding sides is equal and is referred to as scale factor.
Calculation: Consider the two quadrilaterals given below
The scale factor of the given parallelograms as per the above definition can be expressed as,
Considering the first two pairs of ratios,
On cross-multiplication, the value of x can be obtained as,
Now, considering the first and last ratio,
On cross-multiplication, the value of y can be obtained as,
