Question

The length and breadth of a rectangle are (3x-2) and (2x+5) respectively. Find the perimeter and area of the rectangle?​

Answer 1

here's your solution

=>. breadth = (2x + 5)

=> length = ( 3x - 2)

=> perimeter = 2( l + b )

=> perimeter = 2( 3x - 2 + 2x + 5 )

=> perimeter = 2( 5x - 3 )

=> perimeter = 10x - 6

=> area = length*breadth

=> area = (3x - 2) ( 2x + 5)

=> area = 3x(2x+ 5) -2(2x + 5)

=> area = 6x^2 + 15x - 4x - 10

=> area = 6x^2 + 11x - 10

hope it helps

Answer 2

perimeter=2(3x-2)+2(2x+5)

=6x-4+4x+10

=10x+6

area=(3x-2)(2x+5)

=3x(2x+5)-2(2x+5)

=6x²+15x-4x-10

=6x²+11x-10
