Length of a rectangle is 4x²+12x and the area of the rectangle is 24x⁴+72x³, what is the width of the rectangle?

The width is

Step-by-step explanation:

The area of a rectangle is given as :

This implies that:

We have that the length is and the area is

We substitute to get:

We cancel out the common factors to get:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
