A rectangle has a height of 6k^3 and a width of 2k^2 + 4K +5 what is the area

The answer is 12k^5+24k^4+30k^3.

Step-by-step explanation:

You want to multiply the height by width to find area. Multiply 6k^3 times 2k^2+4k+5. 6k^3(2k^2+4k+5)= 12k^5+24k^4+30k^3.

The answer is C

Step-by-step explanation:

Let The width as (w) and lenth as(l)

Then l=3w

When the width increase by 2

Then the New width is w+2

And the lenth increase by 4

Then the New lenth is 3w+4

Then we can find the area
