Question

What is the Area and Perimeter for tbe rectangle?

Answer 1

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`

`= {12n}^(2) - 23n + 10`

now ,

perimeter = 2 ( length + breadth (

= 2 ( 4n-5 + 3n-2)

= 2 ( 7n-7)

= 14n -14

I hopes this helps.
