Answer 1

Answer:

Step-by-step explanation:

1. Area of rectangle = (2x+3y)(3x^2+y)

=6x^3+2xy+9x^2y+3y^2

2.volume of box=l*b*h

=(3x)(2x^2)(7y)

=42x^3y

Answer 2

Answer:

1) 6x^3+2xy+9x^2y+3y^2

2) 42x^3y

Step-by-step explanation:

1) area of rectangle

= l* b

= (2x+3y)* (3x^2+y)

= 6x^3+2xy +9x^2y+ 3y^2

2) vol. of rect.

= l* b* h

=3x * 2x^2 * 7y

= 42x^3y

hope your doubt is cleared now
