Question

Find the area and perimeter of the rectangle ​

Answer 1

Step-by-step explanation:

breadth = breadth

2x +y +1 =12

2x +y =11

breadth=2x+y -11

length =length

4x +y + 2= 3x + 3y

x -2y= -2

so,

length = x-2y+2

now,

perimeter= 2 ( l +b )

=2 ( x-2y +2 +2x +y -11)

=2 (3x - y - 9)

it is required perimeter.

and,

Area= l×b

(x-2y +2) × ( 2x +y -11)

by solving this we get required area ...
