Question

what is the perimeter of rectangle JKLM: J(1,-3) K(1,-4) L(-1,-4) M(-1,-3)

Answer 1

Step-by-step explanation:

use distance formula and then find perimeter

Answer 2

Answer:

Explanation:

The slope m of a line through two points

$(x_1 , y_1)(x_2 , y_2) is given by the formula:</p><p></p><p></p><p></p><p>Δ</p><p>[tex]m \: = \frac{Δy }{Δx}$

So the slopes of the sides of our quadrilateral are:

${M_j_k}$

$\frac{ ( - 1) - 2}{4 - ( - 3)} = \frac{ - 3}{7}$

${M_L_M}$

$\frac{( - 5) - ( - 1)}{2 - 4} = \frac{ - 4}{ - 2} = 2$

similary the other two will also give the same answer ...

So

JK is parallel to LM and

KLis parallel to MJ

So JKLM is a parallelogram.
