Question

The length and breadth of a rectangle are given as (2x+ 3y) and (x - 4). Find the

area and perimeter of the rectangle.​

Answer 1

Step-by-step explanation:

length = 2x+ 3y)

and breadth of a rectangle = (x - 4).

area = length × breadth

=(2x+ 3y) × (x - 4).

= 2x^2-8x +3xy - 12 Y

perimeter= 2(length + breadth)

= 2(2x+ 3y)+ (x - 4))

=2(3x +3y-4)

= 6x + 6y - 8

area of rectangle= 2x^2-8x +3xy - 12 Y

area of rectangle= 2x^2-8x +3xy - 12 Yperimeter of the rectangle= 6x + 6y - 8
