Answer:
Part a) The length of the rectangle is 
Part b) The area of rectangle is 
Step-by-step explanation:
step 1
Find the length
Let
L-----> the length of the rectangle
W---> the width of the rectangle
we know that
The perimeter of rectangle is
so
----> equation A
-----> equation B
substitute equation B in equation A
solve for W
Find the value of L
step 2
Find the area
The area of rectangle is equal to
substitute the values
The 3 angles form the straight line AB. A straight line equals 180 degrees.
The 3 angles when added together need to equal 180:
2x + 65 + (x + 65) = 180
Simplify by combining like terms:
3x + 130 = 180
Subtract 130 from both sides
3x = 50
Divide both sides by 3
X = 50/3
X = 16 2/3 (16.66667 as a repeating decimal)
Now you have x if you need to solve all the angles replace x with its value and sole:
2x = 2(16 2/3) = 33 1/3
X + 65 = 16 2/3 + 65 = 81 2/3
Radius is 12. circumference is equal to 24*pi. Angle CFE is equal to 140.
+ 19 on both sides, -19 becomes 0, 1 becomes 20 x=20
Answer:
40%
Step-by-step explanation:
l2:w3 means that the fraction of land is 2/5.
time 2/5 by 20, you get 40/100
convert 40/100 into percentage is 40%
