Question

The length and breadth of a rectangle r 3xsquare _2 and 2x+5 respectively. Find it's area

Answer 1

Given :

Length of the rectangle = 3x² -2

Breadth of the rectangle = 2x+5

To Find :

It's area

Solution :

Area of rectangle =

Length × Breadth

= (3x²-2) × (2x+5)

= 3x²*2x+3x²*5 -2*2x-2*5

= 6x³+15x²-4x-10

The required area is = 6x³+15x²-4x-10 .

Answer 2

Solution :

We have provided the length and breadth of a rectangle 3x^2 - 2 and 2x + 5 respectively and We need to find the area of a rectangle

*Area of Rectangle*

Area of Rectangle = Length * Breadth

*Substituting the Values in the formula*

⇒ (3x²-2) × (2x+5)

⇒ 3x² * 2x + 3x² * 5  - 2 * 2x-2 * 5

⇒ 6x³ + 15x² - 4x - 10

Therefore , the area of a rectangle is  6x³ + 15x² - 4x - 10
