$41.50 profit
Step-by-step explanation:
First, 1.25x48=60
Second, 60-18.50=41.50
I attached a photo where I graphed these vertices in order to count the length and width. After counting the number of units between R & U I got a width of 4. And then I counted the units between S & T to get a width of 6. Using the formula to calculate the perimeter of a rectangle, P = 2(l+w). The perimeter is 20.
First I added the length plus the width, 4 + 6 and got 10. Then I did 10 x 2 which is how I got a perimeter of 20.
1. 3a=20-2
3a=18
a=6
2. b+1=2
b=2-1
b=1
3. 6y-9-2y=y-3
4y-9=y-3
4y-y=-3+9
3y=6
y=2
4. 2+2+4p=6p
4+4p=6p
4p-6p=-4
-2p=-4
p=2
