The distance between two points on the circumference of a circle is called the arc. If the arc length subtends an angle θ to the center of the circle and the circle has a radius r, then the length of the arc is calculated by the formula;
 θ/360 × 2πr.

The area of a rectangle is found by multiplying the length by the width: A = lw. A certain rectangle has an area of x2 + 7x + 12
kupik [55]

Answer:

Option C is correct

l = x+4 unit and w = x+3 unit

Step-by-step explanation:

Area of a rectangle is given by:

A =lw           ....[1]

where

A is the area of rectangle

l is the length of a rectangle

w is the width of a rectangle.

As per the statement:

A certain rectangle has an area of x^2 + 7x + 12

⇒A = x^2+7x+12

Now factor this trinomial :

A = x^2+4x+3x+12

⇒A = x(x+4)+3(x+4)

⇒A=(x+4)(x+3) unit square

On comparing with [1] we have;

l = x+4 unit and w = x+3 unit

Therefore,the length and width of the rectangle are:

l = x+4 unit and w = x+3 unit
