Answer:
Step-by-step explanation:
we know that
If two figures are similar, then the ratio o its corresponding sides is proportional, and this ratio is called the scale factor
In this problem the corresponding sides are
12 units and 15 units
16 units and n units
therefore
Solve for n
Given equation is :
=0
Taking out common we get,
=0
Now solving this we get,
As 11 is not factor-able, we will solve it using the formula,
a=1 b=5 and c=-11
we get,
and
