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.
factor the trinomial to find the length and width of the rectangle.
l = x + 6; w = x + 2
l = x + 5; w = x + 7
l = x + 4; w = x + 3

Option C is correct

unit and unit

Step-by-step explanation:

Area of a rectangle is given by:

          ....[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

⇒

Now factor this trinomial :

⇒

⇒ unit square

On comparing with [1] we have;

unit and unit

Therefore,the length and width of the rectangle are:

unit and unit

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.
