question
plot and connect the points listed below. when you are done, find the area of the rectangle.
$a(-3,0), b(4,0), c(4, - 3), d(-3,-3)$
answer
attempt 1 out of 2
area = square units

Explanation:

Step1: Find the length of the base

The base is the distance between points $A(-3,0)$ and $B(4,0)$. Using the distance formula for points on a horizontal line (since $y$-coordinates are the same), it is $|4 - (-3)|=7$.

Step2: Find the length of the height

The height is the distance between points $B(4,0)$ and $C(4, - 3)$. Using the distance formula for points on a vertical line (since $x$-coordinates are the same), it is $|0-(-3)| = 3$.

Step3: Calculate the area of the rectangle

The area formula of a rectangle is $A = \text{base}\times\text{height}$. So $A=7\times3 = 21$.

Answer:

$21$
