b. what is the area of the rectangle?

Explanation:

19.

Step1: Calculate absolute values

$$\begin{align*} |6 - 4|&=|2| = 2\\ |3 - 8|&=|-5| = 5 \end{align*}$$

Step2: Subtract the results

$$2-5=-3$$

20.
A.

Step1: Recall the perimeter formula

The perimeter formula for a rectangle is $P = 2(l + w)$, where $l$ is length and $w$ is width.

Step2: Substitute values

Given $l = 11$ inches and $w = 6$ inches, $P=2(11 + 6)=2\times17 = 34$ inches.

B.

Step1: Recall the area formula

The area formula for a rectangle is $A=l\times w$.

Step2: Substitute values

Given $l = 11$ inches and $w = 6$ inches, $A = 11\times6=66$ square inches.

Answer:

1. G. $-3$

A. $34$ inches
B. $66$ square inches
