Chapter 14.5, Problem 34PPS

To determine

To find: The areaof the label of mailing envelope as provided in the problem.

Answer to Problem 34PPS

The area of the label of the mailing envelope is $x^2+7x+12$ .

Explanation of Solution

Given information:

The mailing envelope is mentioned in the problem which has length $l$ , breadth $b$ .

Formula:

Area of the rectangle = $length*breadth$ .

Calculation:

Consider the statement that the mentioned mailing envelope label which has length $l$ , breadth $b$ , height $h$ .

The mentioned mailing label in the problem where $length=x+3$ , $breadth=4x+4$ .

The mentioned mailing envelope is of rectangular in shape.

Recall that Area of the rectangle = $length*breadth$ .

Therefore the area of the label of the mailing envelope is $\left(x+3\right)\left(x+4\right)=x^2+7x+12$ .
