Answer:
Area is: 1,728 inches
Perimeter is: 168 inches
Step-by-step explanation:
Area= Length times width
Perimeter= length plus length plus width plus width.
Perimeter = 2L + 2W
Let x = width and let 2x = length
Perimeter = 66
2x + 2(2x) = 66
2x + 4x = 66 --> 6x = 66 --> x = 66/6 --> x = 11
The width of the rectangle is 11 cm.

Answer:
20
Step-by-step explanation:
straight line is 180 degrees
110+?=180
?=70
y=90 because it is a right angle
All angles of a right triangle added equals 180
so 70+90=160
180-160=20
x=20
