Question

If lenght and breath of a rectangle are 3xy and 4x then find its area​

Answer 1

Answer:

Step-by-step explanation:

Area of the rectangle = length multiply by width

so let length =l

and breadth=b

so A=l*b

A=(3xy)(4x)

$A=12x^2y$ is the area

Answer 2

Answer:

$12x^{2}y$

Step-by-step explanation:

Area of a rectangle is length multiplied by breadth of the rectangle.

Hence, from given -

$3xy(4x)\\12x^{2} y$

is the answer.
