Perimeter = 1020 m
let width be = X
let length be = 20 + 6 (X)
perimeter of rectangle = 2 ( length + width )
1020 = 2 ( 20 + 6 X + X )
1020 = 2 ( 20 + 7 X )
1020 = 40 + 14 X
14 X = 1020 - 40
14 X = 980
X = 980 / 14 = 70
width = X = 70 meters
length = 20 + 6X = 20 + 6 ( 70 )
= 20 + 420
= 440 meters

Answer:
55 degrees
Step-by-step explanation:
First, we can use Thales' Theorem to determine that because AC is along the circle's diameter, angle B (the angle opposite to that side) is a right angle.
Next, we know that an inscribed angle with its vertex on the circle, formed by two intersecting chords (A in this case) is equal to 1/2 of its intercepted arc, so angle A = 70/2=35
We can then use the fact that a triangle adds up to 180 degrees here to get
35+90+C=180
C=55 degrees
1200
you just do 4 multiplied by 6 to get 24 and then multiply 24 by 50 and you have 1200
