The length of a rectangle is six times its width. If the perimeter of the rectangle is 98 yd , find its area.

1 answer:

4 0

P=2(W + L)
p= 2W + 2L
98=2W + 2(6W)
98=2W + 12W
98=W
98/14=14W/14
W=7

L= 6W
L = 6(7)
L= 42

CHECK
p=2(7 +42)
p=2(49)
p= 98

Area of a rectangle = W X L
Area of a rectangle = 7 X 42
Area of a rectangle = 294

Graph the image of kite ABCD after a rotation 180° counterclockwise around the origin.

rewona [7]

Solution:

Given a kite ABCD on a graphhh, with the coordinates given below

$\begin{gathered} A(-8,-6) \\ B(-7,-2) \\ C(-1,-6) \\ D(-7,-10) \end{gathered}$

If the kite is rotated 180° counterclockwise around the origin,

The rule for a rotation 180° counterclockwise around the origin is

$(x,y)\rightarrow(-x,-y)$

The coordinates of the kite after the rotation of 180° counterclockwise around the origin will be

$\begin{gathered} A(-8,-6)\rightarrow A^{\prime}(8,6) \\ B^{\prime}(-7,-2)\rightarrow B^{\prime}^(7,2) \\ C(-1,-6)\rightarrow C^{\prime}(1,6) \\ D(-7,-10)\rightarrow D^{\prime}(7,10) \end{gathered}$

The graph is shown below
