Question

the length and breadth of a rectangle are 3x²+2 and 2x+5. Find the area

​

Answer 1

3x²+2(*2x+5)= 6x³+4x+15x²+10 ans

Answer 2

Answer:

6x³+15x²+4x+10

Step-by-step explanation:

length =3x²+2

breadth =2x+5

area of a rectangle = (length × breadth)

= (3x²+2) × (2x+5)

=2x(3x²+2) + 5(3x²+2)

=6x³+4x+15x²+10

=6x³+15x²+4x+10
