Given :-
length of rectangle = ( 4n-5 )
breadth of rectangle = ( 3n-2)
To find :-
Area and perimeter of rectangle.
solution :-
by the question ,
We know the area of rectangle = length × breadth
Area = (4n -5) (3n-2)
![= {12n}^(2) - 8n - 15n + 10](https://img.qammunity.org/2022/formulas/mathematics/high-school/znzx04wq35bxav4b9xn84e2k7zrzdag2qz.png)
![= {12n}^(2) - 23n + 10](https://img.qammunity.org/2022/formulas/mathematics/high-school/16j62yn85pe9sacn01k8ptxa610n9rws77.png)
now ,
perimeter = 2 ( length + breadth (
= 2 ( 4n-5 + 3n-2)
= 2 ( 7n-7)
= 14n -14
I hopes this helps.
