3. the ratio of the corresponding side lengths of two similar parallelogram
signs is 9: 14.
a. what is the ratio of the perimeters? explain.

The ratio of perimeters is 1 : 1

Step-by-step explanation:

Given as :

The ratio of corresponding sides length of two parallelogram = 9:14

So, Let The Lengths of the opposite sides of parallelogram = 9 x

And The breadth of the opposite sides of parallelogram = 14 x

Let The perimeter of parallelogram = P

Now, for Parallelogram , its opposite sides are parallel and equal

∴ Perimeter of  Parallelogram = 2 × Length + 2 × breadth

or,  Perimeter of  Parallelogram = 2 × 9 x + 2 × 14 x

or,  Perimeter of  Parallelogram = 18 x + 28 x

or, Perimeter of  Parallelogram = 46 x

Now, Since both the parallelogram have same side length ratio , so

The perimeter of both is same = 46 x

So , =

Or,   =1 : 1

Hence The ratio of perimeters = 1 : 1    Answer

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
