Answer:
Part a) The length of the mat is 
Part b) The area of the mat 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
Answer:
B. M Y, G T, B W, segment MG segment YT, segment GB segment TW, segment MB segment YW
C. M T, G W, B Y, segment MG segment TW, segment GB segment WY, segment MB segment TY

As you get older your brain develops as you do so when you’re taught math your brain is developing a slightly slower pace than it should be for example if you have a teacher who doesn’t really teach a lot it’s really going to slow down the process of learning
So the larger number is x, and the smaller number is y
7y=x
3x=7+4y
(So plug in the 7y=x information into the second equation)
3(7y)=7+4y
21y=7+4y
17y=7
y=7/17
