Answer:

A = 12n^4-15n^3-3n^2

Step-by-step explanation:

The dimensions of a rectangle are length and breadth/width

Here we are given height . Assuming it to be one of the side of the rectangle , we will do the further calculation

Hence one side is

side 1 = 3n^2

And the other side is

Side 2 = 4n^2-5n-1

The area of rectangle = side 1 x side 2

A=3n^2 \times (4n^2-5n-1)

A=3n^2 \times 4n^2-3n^2 \times 5n-3n^2 \times 1

A=3 \times 4 \times n^2 \times n^2- 3 \times 5 \times n^2 \times n - 3n^2

A = 12n^4-15n^3-3n^2

Hence area can be given as expression

A = 12n^4-15n^3-3n^2
