Answer:
number 12 is
Answer:
Option D. No,they are not similar because their side lengths are not proportional.
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem If the rectangles are similar
then
The ratio of its corresponding lengths must be equal to the ratio of its corresponding heights
<u><em>Verify</em></u>
therefore
The rectangles are not similar because their side lengths are not proportional.
<h2><u>Given</u><u> </u><u>:</u><u>-</u></h2>
length of rectangle = ( 4n-5 )
breadth of rectangle = ( 3n-2)
<h2><u>To</u><u> </u><u>find</u><u> </u><u>:</u><u>-</u></h2>Area and perimeter of rectangle.
<h2><u>solution</u><u> </u><u>:</u><u>-</u></h2>by the question ,
We know the area of rectangle = length × breadth
Area = (4n -5) (3n-2)
now ,
perimeter = 2 ( length + breadth (
= 2 ( 4n-5 + 3n-2)
= 2 ( 7n-7)
= 14n -14
