Answer:

Step-by-step explanation:

rectangle area = 144 cm

Formula: A= L*H

The give the length which is 16

144 = 16*H

Since they gave u the area instead of the height, work backwards

144/16 = 16/16 *H

9 = H

Now you have the length and height

Length: 16

Height: 9

Perimeter is when you add up all the sides

The top and bottom of the rectangle is the length which is 16 so

16 + 16 = 32

The left and right side of the rectangle is the height which is 9 so

9 + 9 = 18

Now add then both

32 + 18 = 50

So the perimeter of the rectangle is 50

Hope this helped!

Transformations can be thought of as functions that take the points from one object (the pre-image) to the corresponding points

sweet-ann [11.9K]

1. Translation of a units to the right and b units up has rule:

(x,y)→(x+a,y+b).

Then the function is

$T(x,y)=(x+a,y+b).$

2. Reflection across the y-axis acts in following way:

(x,y)→(-x,y).

Then the function is

$R_y(x,y)=(-x,y).$

3. Reflection across the x-axis acts in following way:

(x,y)→(x,-y).

Then the function is

$R_x(x,y)=(x,-y).$

4. Rotation of 90 degrees counterclockwise about the origin, point O acts bu the rule:

(x,y)→(-y,x).

Then the function is

$R_{O,90^{\circ}}(x,y)=(-y,x).$

5. Rotation of 180 degrees counterclockwise about the origin, point O acts bu the rule:

(x,y)→(-x,-y).

Then the function is

$R_{O,180^{\circ}}(x,y)=(-x,-y).$

6. Rotation of 270 degrees counterclockwise about the origin, point O acts bu the rule:

(x,y)→(y,-x).

Then the function is

$R_{O,270^{\circ}}(x,y)=(y,-x).$
