Answer:

Step-by-step explanation:
Given:



(segment addition postulate)
(substitution)
(subtracting 17 from each side)

(Subtracting 5y from both sides)


(dividing both sides by -2)

Plug in the value of y

Answer:263 square units
Step-by-step explanation:
No work needed
First one :
We divide it into two rectangles (the top one has dimensions 2in*4in)
The area of the top rectangle is 2*4=8 in^2
The second rectangle has dimensions 3*(5-3)=6 in^2
Hence the total area is 8+6=14 square inches
Second one :
We divide it into a rectangle (dimensions 11*17) and a triangle on the top.
The area of the rectangle is 11*17=187 m^2
The rectangle has dimensions 17 (base's length) and 23-11 (height) hence its area is 17*(23-11)/2=102 m^2
Hence the total area is 102+187=289 square meters
Let the width =x
length = 6x
p=14x
28=14x
x=2
