Question

The length and breadth of a rectangle is 3x²-2 and 2x+5 respectively, find its
area

Answer 1

Answer:

The area of the rectangle is $6x^{3}+15x^{2}-4x-10$.

Step-by-step explanation:

The area of a rectangle is: $Area=length\times breadth$

Given: Length = 3x² - 2 and breadth = 2x + 5.

The area of the rectangle is:

$Area=length\times breadth\\=(3x^{2}-2)(2x+5)\\=6x^{3}+15x^{2}-4x-10$

Thus, the area of the rectangle is $6x^{3}+15x^{2}-4x-10$.
