Answer:
Perimeter: 60.6cm
Area: 212.3cm
Step-by-step explanation:
When calulating the perimeter, you are adding the length of all the sides together. Since the figure is a rectangle, two two pairs of sides will be different lengths. Solving is as follows:
P= 11+11+19.3+19.3 or P=11(2)+19.3(2) =60.6
With area, you need the total amount of mass, so you would multiply two sides. In this case, the two are 11cm and 19.3cm.
A= 11(19.3)cm =212.3
Answer:

Answer: Malik's total profit is $213
Step-by-step explanation:
2 * 45 = 90
2 * 65 = 130
130 - 90 = 40
3 * 85 = 255
3 * 126 = 378
378 - 255 = 123
5 * 5 = 25
5 * 15 = 75
75 - 15 = 50
50 + 40 + 123 = 213
I think it is 1/2. (just filling the 20 characters now)
36/2=18
18/14+c +18/14-c=2.8
18(14-c)+18(14+c)=2.8(196-c²)
504=548.8-2.8c²
2.8c²=44.8
c²=16
c=±4
The current flows at 4 mph
