Question

The formula for the area of a rectangle is A = lw. What

Answer 1

Answer:

20 square units

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

In this problem

$L=WX=ZY\\W=WZ=XY$

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

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

Find the distance WX

we have

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

substitute the values in the formula

$d=\sqrt{(3-1)^{2}+(3+3)^{2}}$

$d=\sqrt{(2)^{2}+(6)^{2}}$

$d_W_X=\sqrt{40}\ units$

Find the distance XY

we have

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

substitute the values in the formula

$d=\sqrt{(0-3)^{2}+(4-3)^{2}}$

$d=\sqrt{(-3)^{2}+(1)^{2}}$

$d_X_Y=\sqrt{10}\ units$

Find the area of rectangle

$A=(WX)(XY)$

substitute the values

$A=(\sqrt{40})(\sqrt{10})=20\ units^2$
