The formula for the area of a rectangle is A lw What is the area of rectangle WXYZ 16 square units 18 square units 20

Answer :

Answer:

20 square units

Step-by-step explanation:

we know that

The area of rectangle is equal to

[tex]A=LW[/tex]

In this problem

[tex]L=WX=ZY\\W=WZ=XY[/tex]

the formula to calculate the distance between two points is equal to

[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]

Find the distance WX

we have

W(-3,1), X(3,3)

substitute the values in the formula

[tex]d=\sqrt{(3-1)^{2}+(3+3)^{2}}[/tex]

[tex]d=\sqrt{(2)^{2}+(6)^{2}}[/tex]

[tex]d_W_X=\sqrt{40}\ units[/tex]

Find the distance XY

we have

X(3,3),Y(4,0)

substitute the values in the formula

[tex]d=\sqrt{(0-3)^{2}+(4-3)^{2}}[/tex]

[tex]d=\sqrt{(-3)^{2}+(1)^{2}}[/tex]

[tex]d_X_Y=\sqrt{10}\ units[/tex]

Find the area of rectangle

[tex]A=(WX)(XY)[/tex]

substitute the values

[tex]A=(\sqrt{40})(\sqrt{10})=20\ units^2[/tex]
