Arectangle has a height of 3 and a width of 4b^4+2b-6.
express the area of the entire rectangle.

12b^4 + 6b - 18

Step-by-step explanation:

Area of a rectangle is width x height

(4b^4 + 2b - 6) x 3

Multiply the coefficients by 3

So you get

12b^4 + 6b - 18

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
