Question

write the expression for the perimeter of a rectangle with length 2x²+5x and width 8x²-3x​

Answer 1

Answer:

Given that ;

Length of the Rectangle = 2x²+5x

Breadth of the Rectangle = 8x²-3x

Perimeter = ?

Formula :

Perimeter of the Rectangle ;

P = 2 ( l + b )

Substitute L & b values :

P = 2 ( 2x²+5x + 8x²-3x )

P = 2 ( 10x² + 2x )

P = 20x² + 4x

Hence ;

Required Expression :

Perimeter = 20x² + 4x
