Find Rectangle Dimensions with Given Perimeter and Area

#RectangleAreaPerimeterRelation #globalmathinstitute #anilkumarmath
Area and perimeter of a rectangle are related and so many important questions are based on this. Many of then use factoring quadratic equations or solving them using quadratic formula

pov: you never listened in class and we're doing tests online

I have looked at several videos for this problem but this may be the first one that I found that works.

[zazamccormack]

Thank you! My teacher did not teach me about this. But these kinds of questions are in my worksheets.

Why is the 33 not -33 when it goes to the equal?

[snnr]

this man has taught me 3 weeks worth of lessons in 1 video this school system is cringe man

[NantumeZam]

😅😅😅😅😅😅 oh my God thanks for the gift of this man

[BavakureGilbert-ut]

Why don't you change the sign for 33 when it change the position?

May god, the universe who ever bless you
My math textbook didn’t even teach me this and my teacher is no help thank you so much

[oneechan]

This is very helpful up until now. Thanks for sharing ur knowledge sir.

If area of a rectangle is 32squares ft .what its side . please solve

[jarisestraza]

pls help me to solve the problem finding the dimensions of a rectangle where the only given is the area which is 24x^2 + 60x

[mattu]

This was very helpful. Thank you so much!

[uraaxeecaqligaaga]

Thank you sir I'm really greatful to you God bless you

[eiteiei]

You're better at teaching than my teacher is. Thanks!

The perimeter of a rectangular is 44m and its area is 112m^2. Find the dimensions of the rectangular lot.

[mamdoo]

thank you soo much, much love and support this helped me get a full mark on my pre-calculus test!

[keizrmabagos]

What if the perimeter is 36 and the area is 80

[lettuce]

Can you also solve this one?
A rectangular parking lot must have a perimeter of 440 feet and an area of at least 8000 square feet.What are the possible dimensions of the parking lot.

Not a good tactic to decimalize the quadratic coefficients at the start.
Using a slightly unconventional method for solving the quadratic.
L^2-23/2*L+33 = 0.
m=23/4 d = sqrt( m^2 - 33) -> d = 1/4
and the roots are :
m-d and m+d -> 23/4 -1/4 and 23/4 + 1/4 -> (11/2, 6 ) -> L
