Question

A rectangle has a width of (3x² – 5x – 2) units and a length of (2x² + 12x - 4) units. Create a simplified expression of the form ax+ bx + c for the perimeter of the rectangle.

Perimeter = ........... units ​

Answer 1

b=(3x² – 5x – 2)

l=(2x² + 12x - 4)

perimeter= 2(l+b)

=2( 2x² + 12x - 4+3x² – 5x – 2)

=2(5x²+7x-6)

=(10x²+14x-12) units

Hope it helps:-)
